  • [ 11 C]acetate PET as a tool for diagnosis of liver steatosis
    • Authors: Marzieh Nejabat; Asha Leisser; Georgios Karanikas; Wolfgang Wadsak; Markus Mitterhauser; Marius Mayerhöfer; Christian Kienbacher; Michael Trauner; Marcus Hacker; Alexander R. Haug
      Abstract: Purpose To investigate [11C]acetate PET-surrogate parameter of fatty acid synthase activity—as suitable tool for diagnosis and monitoring of liver steatosis. Methods In this retrospective study, data were obtained from 83 prostatic carcinoma patients from 1/2008 to 1/2014. Mean HU was calculated from unenhanced CT of all patients from liver with liver HU less than 40 as threshold for liver steatosis. SUVmax of the liver and of the blood pool in thoracic aorta (as background for calculation of a liver/background ratio [SUVl/b]) was measured. t test was used with a P < 0.05 considered as statistically significant difference and ROC analysis was used for calculating specificity and sensitivity. Results 19/83 patients (20%) had diagnosis of hepatic steatosis according to CT. Uptake of [11C]acetate was significantly higher in patients with hepatic steatosis as compared to control group (SUVmax 7.96 ± 2.0 vs. 5.48 ± 2.3 [P < 0.001]). There was also a significant correlation between both SUVmax (r = − 0.52, P < 0.001) and SUVl/b (r = − 0.59, P < 0.001) with the density (HU) of the liver. In ROC analysis for detection of liver steatosis SUVmax (threshold: 5.86) had a sensitivity of 94% and specificity of 69% with an AUC of 0.81. Increasing body mass index is correlated with the severity of steatosis. Conclusion We showed for the first time that hepatic steatosis associates with increased [11C]acetate uptake. Also, severity of steatosis correlates with [11C]acetate uptake. [11C]acetate uptake PET seems promising for the assessment of liver steatosis.

  • Utility of the portal venous phase for diagnosing pancreatic necrosis in
           acute pancreatitis using the CT severity index
    • Authors: Yoshifumi Noda; Satoshi Goshima; Keita Fujimoto; Hiroshi Kawada; Nobuyuki Kawai; Yukichi Tanahashi; Masayuki Matsuo
      Abstract: Purpose The purpose of the study was to evaluate the value of portal venous phase (PVP) images in the diagnosis of pancreatic necrosis in patients with acute pancreatitis using computed tomography severity index (CTSI). Methods This retrospective study was approved by our Institutional Review Board, and written informed consent was waived. Dynamic contrast-enhanced CT images, with the pancreatic parenchymal phase (PPP) and the PVP, were obtained from 56 consecutive patients with acute pancreatitis. Two radiologists reviewed two sets of images, namely PPP images alone (image set A) and combined PPP and PVP images (image set B) to evaluate the CTSI. Cases were categorized as necrotizing pancreatitis if ensuing walled-off necrosis formation was identified 4 weeks after onset of symptoms. The relationship between pancreatic necrosis and CTSI was compared between image sets A and B. Logistic regression analysis was performed to evaluate the significance of clinical and radiological factors associated with the diagnosis of pancreatic necrosis. Results Pancreatic necrosis was confirmed in 14 out of 56 (25%) patients. The area under the receiver-operating-characteristic curve (AUC) for the diagnosis of pancreatic necrosis was 0.70 and 0.78 for image sets A and B, respectively. The AUC for image set B was significantly greater than that for image set A (P = 0.0002). Logistic regression analysis demonstrated that among clinical and radiological factors tested, CTSI for image set B was independently correlated with pancreatic necrosis (P = 0.025). Conclusions Combined PPP and PVP images significantly improved the diagnostic accuracy of pancreatic necrosis following acute pancreatitis.

  • Small bowel obstruction and the gastrografin challenge
    • Authors: Robert D’Agostino; Naiim S Ali; Sergey Leshchinskiy; Anjuli R Cherukuri; Judy K Tam
      Abstract: The “gastrografin challenge” has been used for decades in the evaluation of small bowel obstruction (SBO). This type of study involves enteric administration of a water-soluble contrast followed by serial abdominal radiographs. While its diagnostic role is well established, its therapeutic role remains controversial. Following an algorithm for gastrografin challenge cases can help with interpretation. An understanding of the appearance of diluted contrast in the small bowel, the concentrating effect of contrast in the colon, and knowledge of surgical history and anatomy is paramount for diagnosis. In this article, we review the approach to acute SBO and the use of gastrografin along with reviewing image interpretation of cases of partial and complete SBO. Gastrografin use in adynamic ileus along with other potential future uses is also discussed.

  • Hepatopulmonary shunting on Tc99m-MAA liver mapping: correlation with
           dynamic cross-sectional imaging and description of different shunting
    • Authors: Mohammed Bermo; Manuela C. Matesan; Malak Itani; Fatemeh Behnia; Hubert J. Vesselle
      Abstract: Purpose The purpose of the study was to correlate lung shunt fraction (LSF) calculated by intra-arterial injection of Technetium-99m (Tc-99m)-labeled macroaggregated albumin (MAA) in a hepatic artery branch with the presence of certain patterns of vascular shunts on dynamic CT or MRI of the liver. Methods This retrospective study was approved by the institutional review board and informed consent was waived. We reviewed 523 MAA scans in 453 patients (301 men, 152 women) performed from July 2007 to June 2015 and their correlative cross-sectional imaging. Patterns of vascular shunts on dynamic CT or MRI performed within 3 months of the MAA study and that potentially divert hepatic arterial inflow to the systemic venous return were defined as “target shunts.” Dynamic CT or MRI was classified into three groups with target shunt present, absent, or indeterminate. The mean LSF was compared across the first and second groups using paired t test. Results 342 CT and MRI studies met inclusion criteria: target shunts were present in 63 studies, absent in 271 studies, and 8 studies were indeterminate. When target shunts were visualized, the mean LSF on corresponding MAA scans was 12.9 ± 10.36% (95% CI 10.29–15.15%) compared to 4.3 ± 3.17% (95% CI 3.93–4.68%) when no target shunt was visualized. The difference was statistically significant (p value < 0.001). Identified target shunts were either direct (arteriohepatic venous shunt) or indirect (arterioportal shunt combined with a portosystemic shunt). Conclusions Visualizing certain patterns of vascular shunting on a dynamic CT or MRI scan is associated with high LSF.

  • Advanced ultrasound applications in the assessment of renal transplants:
           contrast-enhanced ultrasound, elastography, and B-flow
    • Authors: Tara A. Morgan; Priyanka Jha; Liina Poder; Stefanie Weinstein
      Abstract: Ultrasound is routinely used as the first imaging exam for evaluation of renal transplants and can identify most major surgical complications and evaluate vascularity with color Doppler. Ultrasound is limited, however, in the detection of parenchymal disease processes and Doppler evaluation is also prone to technical errors. Multiple new ultrasound applications have been developed and are under ongoing investigation which could add additional diagnostic capability to the routine ultrasound exam with minimal additional time, cost, and patient risk. Contrast-enhanced ultrasound (CEUS) can be used off-label in the transplant kidney, and can assist in detection of infection, trauma, and vascular complications. CEUS also can demonstrate perfusion of the transplant assessed quantitatively with generation of time–intensity curves. Future directions of CEUS include monitoring treatment response and microbubble targeted medication delivery. Elastography is an ultrasound application that can detect changes in tissue elasticity, which is useful to diagnose diffuse parenchymal disease, such as fibrosis, otherwise unrecognizable with ultrasound. Elastography has been successfully applied in other organs including the liver, thyroid, and breast; however, it is still under development for use in the transplant kidney. Unique properties of the transplant kidney including its heterogeneity, anatomic location, and other technical factors present challenges in the development of reference standard measurements. Lastly, B-flow imaging is a flow application derived from B-mode. This application can show the true lumen size of a vessel which is useful to depict vascular anatomy and bypasses some of the pitfalls of color Doppler such as demonstration of slow flow.

  • Magnetic resonance imaging (MRI) of the renal sinus
    • Authors: Satheesh Krishna; Nicola Schieda; Trevor A. Flood; Alampady Krishna Shanbhogue; Subramaniyan Ramanathan; Evan Siegelman
      Abstract: This article presents methods to improve MR imaging approach of disorders of the renal sinus which are relatively uncommon and can be technically challenging. Multi-planar Single-shot T2-weighted (T2W) Fast Spin-Echo sequences are recommended to optimally assess anatomic relations of disease. Multi-planar 3D-T1W Gradient Recalled Echo imaging before and after Gadolinium administration depicts the presence and type of enhancement and relation to arterial, venous, and collecting system structures. To improve urographic phase MRI, concentrated Gadolinium in the collecting systems should be diluted. Diffusion-Weighted Imaging (DWI) should be performed before Gadolinium administration to minimize T2* effects. Renal sinus cysts are common but can occasionally be confused for dilated collecting system or calyceal diverticula, with the latter communicating with the collecting system and filling on urographic phase imaging. Vascular lesions (e.g., aneurysm, fistulas) may mimic cystic (or solid) lesions on non-enhanced MRI but can be suspected by noting similar signal intensity to the blood pool and diagnosis can be confirmed with MR angiogram/venogram. Multilocular cystic nephroma commonly extends to the renal sinus, however, to date are indistinguishable from cystic renal cell carcinoma (RCC). Solid hilar tumors are most commonly RCC and urothelial cell carcinoma (UCC). Hilar RCC are heterogeneous, hypervascular with epicenter in the renal cortex compared to UCC which are centered in the collecting system, homogeneously hypovascular, and show profound restricted diffusion. Diagnosis of renal sinus invasion in RCC is critically important as it is the most common imaging cause of pre-operative under-staging of disease. Fat is a normal component of the renal sinus; however, amount of sinus fat correlates with cardiovascular disease and is also seen in lipomatosis. Fat-containing hilar lesions include lipomas, angiomyolipomas, and less commonly other tumors which engulf sinus fat. Mesenchymal hilar tumors are rare. MR imaging diagnosis is generally not possible, although anatomic relations should be described to guide diagnosis by percutaneous biopsy or surgery.

  • Contrast-enhanced ultrasonography in interventional oncology
    • Authors: Sriharsha Gummadi; John R. Eisenbrey; Andrej Lyshchik
      Abstract: Contrast-enhanced ultrasound (CEUS) has evolved from the use of agitated saline to second generation bioengineered microbubbles designed to withstand insonation with limited destruction. While only one of these newer agents is approved by the Food and Drug Administration for use outside echocardiography, interventional radiologists are increasingly finding off-label uses for ultrasound contrast agents. Notably, these agents have an extremely benign safety profile with no hepatic or renal toxicities and no radiation exposure. Alongside diagnostic applications, CEUS has begun to develop its own niche within the realm of interventional oncology. Certainly, the characterization of focal solid organ lesions (such as hepatic and renal lesions) by CEUS has been an important development. However, interventional oncologists are finding that the dynamic and real-time information afforded by CEUS can improve biopsy guidance, ablation therapy, and provide early evidence of tumor viability after locoregional therapy. Even more novel uses of CEUS include lymph node mapping and sentinel lymph node localization. Critical areas of research still exist. The purpose of this article is to provide a narrative review of the emerging roles of CEUS in interventional oncology.

  • Dual-layer spectral detector CT: non-inferiority assessment compared to
           dual-source dual-energy CT in discriminating uric acid from non-uric acid
           renal stones ex vivo
    • Abstract: Purpose To assess the non-inferiority of dual-layer spectral detector CT (SDCT) compared to dual-source dual-energy CT (dsDECT) in discriminating uric acid (UA) from non-UA stones. Methods Fifty-seven extracted urinary calculi were placed in a cylindrical phantom in a water bath and scanned on a SDCT scanner (IQon, Philips Healthcare) and second- and third-generation dsDECT scanners (Somatom Flash and Force, Siemens Healthcare) under matched scan parameters. For SDCT data, conventional images and virtual monoenergetic reconstructions were created. A customized 3D growing region segmentation tool was used to segment each stone on a pixel-by-pixel basis for statistical analysis. Median virtual monoenergetic ratios (VMRs) of 40/200, 62/92, and 62/100 for each stone were recorded. For dsDECT data, dual-energy ratio (DER) for each stone was recorded from vendor-specific postprocessing software (Syngo Via) using the Kidney Stones Application. The clinical reference standard of X-ray diffraction analysis was used to assess non-inferiority. Area under the receiver-operating characteristic curve (AUC) was used to assess diagnostic performance of detecting UA stones. Results Six pure UA, 47 pure calcium-based, 1 pure cystine, and 3 mixed struvite stones were scanned. All pure UA stones were correctly separated from non-UA stones using SDCT and dsDECT (AUC = 1). For UA stones, median VMR was 0.95–0.99 and DER 1.00–1.02. For non-UA stones, median VMR was 1.4–4.1 and DER 1.39–1.69. Conclusion SDCT spectral reconstructions demonstrate similar performance to those of dsDECT in discriminating UA from non-UA stones in a phantom model.

  • MR elastography in primary sclerosing cholangitis: correlating liver
           stiffness with bile duct strictures and parenchymal changes
    • Abstract: Aim To determine correlation of liver stiffness measured by MR Elastography (MRE) with biliary abnormalities on MR Cholangiopancreatography (MRCP) and MRI parenchymal features in patients with primary sclerosing cholangitis (PSC). Methods Fifty-five patients with PSC who underwent MRI of the liver with MRCP and MRE were retrospectively evaluated. Two board-certified abdominal radiologists in agreement reviewed the MRI, MRCP, and MRE images. The biliary tree was evaluated for stricture, dilatation, wall enhancement, and thickening at segmental duct, right main duct, left main duct, and common bile duct levels. Liver parenchyma features including signal intensity on T2W and DWI, and hyperenhancement in arterial, portal venous, and delayed phase were evaluated in nine Couinaud liver segments. Atrophy or hypertrophy of segments, cirrhotic morphology, varices, and splenomegaly were scored as present or absent. Regions of interest were placed in each of the nine segments on stiffness maps wherever available and liver stiffness (LS) was recorded. Mean segmental LS, right lobar (V–VIII), left lobar (I–III, and IVA, IVB), and global LS (average of all segments) were calculated. Spearman rank correlation analysis was performed for significant correlation. Features with significant correlation were then analyzed for significant differences in mean LS. Multiple regression analysis of MRI and MRCP features was performed for significant correlation with elevated LS. Results A total of 439/495 segments were evaluated and 56 segments not included in MRE slices were excluded for correlation analysis. Mean segmental LS correlated with the presence of strictures (r = 0.18, p < 0.001), T2W hyperintensity (r = 0.38, p < 0.001), DWI hyperintensity (r = 0.30, p < 0.001), and hyperenhancement of segment in all three phases. Mean LS of atrophic and hypertrophic segments were significantly higher than normal segments (7.07 ± 3.6 and 6.67 ± 3.26 vs. 5.1 ± 3.6 kPa, p < 0.001). In multiple regression analysis, only the presence of segmental strictures (p < 0.001), T2W hyperintensity (p = 0.01), and segmental hypertrophy (p < 0.001) were significantly associated with elevated segmental LS. Only left ductal stricture correlated with left lobe LS (r = 0.41, p = 0.018). Global LS correlated significantly with CBD stricture (r = 0.31, p = 0.02), number of segmental strictures (r = 0.28, p = 0.04), splenomegaly (r = 0.56, p < 0.001), and varices (r = 0.58, p < 0.001). Conclusion In PSC, there is low but positive correlation between segmental LS and segmental duct strictures. Segments with increased LS show T2 hyperintensity, DWI hyperintensity, and post-contrast hyperenhancement. Global liver stiffness shows a moderate correlation with number of segmental strictures and significantly correlates with spleen stiffness, splenomegaly, and varices.

  • Three cases of intracystic papillary neoplasm of gallbladder
    • Abstract: Intracystic papillary neoplasm (ICPN) of gallbladder is a comparatively new concept and is described as pre-malignant lesions in Nakanuma et al. (In: Bosman et al. (eds) WHO Classification of Tumours of the Digestive System, World Health Organization of Tumours, IARC, Lyon, 2010). ICPN with high-grade intraepithelial neoplasia is understood to include intraepithelial carcinoma or noninvasive carcinoma. And lesions with invasive cancer components are classified as ICPN with an associated invasive carcinoma [1]. According to Adsay et al., more than half of patients diagnosed with ICPN have invasive cancer components (Adsay et al., Am J Surg Pathol 36:1279–1301, 2012). Polypoid masses in the gallbladder including benign, malignant, and non-neoplastic lesions have been called gallbladder polyps, and ICPN is also a polypoid lesion in the gallbladder. However, it is difficult to differentiate between them. In the literature, it is said that the possibility of malignancy is high in lesions exceeding 1 cm (Terzi et al., Surgery 127:622–627, 2000). And there are few reports on characteristic imaging findings of ICPN. We have experienced three cases (two females and one male) of ICPN and report our imaging findings. Contrast-enhanced computed tomography revealed large papillary polypoid lesions approximately 2–4 cm in size in the gallbladder. Findings suggestive of deformation of the gallbladder wall and extrinsic progression were absent in all cases. T2-weighted magnetic resonance imaging revealed intense signals and diffusion-weighted imaging showed high intensity. Expanding of the gallbladder was seen in case 1, and a tumor stalk-like appearance was seen in the papillary mass in cases 2 and 3. Surgery was performed in all three cases and ICPN was diagnosed pathologically. The cancer was localized to the mucosa, with no infiltration of surrounding tissue in all three cases.

  • Neuroblastic tumors in young adults as a sequela of malignant
           neuroblastoma: report of two cases
    • Authors: Takuya Adachi; Minato Yokoyama; Yasuhisa Fujii; Yuko Kinowaki; Susumu Kirimura; Kazunori Kubota; Yukihisa Saida; Ukihide Tateishi
      Abstract: Neuroblastoma, ganglioneuroblastoma, and ganglioneuroma share the same histological spectrum which originates from neural crest cells. We present herein two young adult patients with neuroblastic tumors with lymph node metastases. Both the patients were diagnosed incidentally as having retroperitoneal masses, which showed little or no immature cells despite coexistence of lymph node involvement. The tumors were considered to represent spontaneous regression of malignant neuroblastoma. Radiologists should consider the possibility of spontaneous regression of neuroblastic tumors, when poorly enhanced multi-component masses at the retroperitoneum with lymph node involvement are visualized.

  • Impact of formal training on agreement of videofluoroscopic swallowing
           study interpretation across and within disciplines
    • Authors: Alice K. Silbergleit; Diana Cook; Scott Kienzle; Erica Boettcher; Daniel Myers; Denise Collins; Edward Peterson; Matthew A. Silbergleit; Richard Silbergleit
      Abstract: Purpose Formal agreement studies on interpretation of the videofluoroscopic swallowing study (VFSS) procedure among speech-language pathologists, radiology house officers, and staff radiologists have not been pursued. Each of these professions participates in the procedure, interprets the examination, and writes separate reports on the findings. The aim of this study was to determine reliability of interpretation between and within the disciplines and to determine if structured training improved reliability. Methods Thirteen speech-language pathologists (SLPs), ten diagnostic radiologists (RADs) and twenty-one diagnostic radiology house officers (HOs) participated in this study. Each group viewed 24 VFSS samples and rated the presence or absence of seven aberrant swallowing features as well as the presence of dysphagia and identification of oral dysphagia, pharyngeal dysphagia, or both. During part two, the groups were provided with a training session on normal and abnormal swallowing, using different VFSS samples from those in part one, followed by re-rating of the original 24 VFSS samples. A generalized estimating equations (GEE) approach with a binomial link function was used to examine each question separately. For each cluster of tests, as example, all pairwise comparisons between the three groups in the pretraining period, a Hochberg’s correction for multiple testing was used to determine significance. A GEE approach with a binomial link function was used to compare the premeasure to postmeasure for each of the three groups of raters stratified by experience. Results The primary result revealed that the HO group scored significantly lower than the SLP and RAD group on identification of the presence of dysphagia (p = 0.008; p = 0.001, respectively), identification of oral phase dysphagia (p = 0.003; p = 0.001, respectively), and identification of both oral and pharyngeal phase dysphagia, (p = 0.014, p = 0.001, respectively) pretraining. Post training there was no statistically significant difference between the three groups on identification of dysphagia and identification of combined oral and pharyngeal dysphagia. Conclusions Formal training to identify oropharyngeal dysphagia characteristics appears to improve accuracy of interpretation of the VFSS procedure for radiology house officers. Consideration to include formal training in this area for radiology residency training programs is recommended.

  • Grade 2 pancreatic neuroendocrine tumors: overbroad scope of Ki-67 index
           according to MRI features
    • Authors: Yabin Hu; Shengxiang Rao; Xiaolin Xu; Yibo Tang; Mengsu Zeng
      Abstract: Purpose To evaluate the value of MR imaging features in stratifying Grade 2 (G2) pancreatic neuroendocrine tumors (PNETs) using the 5% cut-off value of the Ki-67 index as reference standards. Materials and methods Between January 2010 and October 2016, 41 G2 PNET patients (One patient had 3 tumors) with preoperative MR imaging were included. Tumor grading was based on the revised 2016 World Health Organization classification of PNETs. MR imaging features included size, shape, consistency, T1-w and T2-w signal intensities, enhancement pattern, apparent diffusion coefficient (ADC) ratios (tumor/normal pancreatic parenchyma). Results 16 Ki-67 index < 5% tumors (SKIT, 37.2%) and 27 Ki-67 index ≥ 5% tumors (LKIT, 62.8%) of G2 were evaluated. The LKIT showed solid consistency (85% vs. 50%, P < 0.05), incomplete envelope-like reinforcement in a delayed phase (74% vs. 62%, P < 0.05), and liver or lymph node metastases (67% vs. 31%, P < 0.05) more frequently than did SKIT. However, ADC ratios of LKIT were smaller than SKIT (0.85 ± 0.23 vs. 1.29 ± 0.39, P = 0.001). Using binary logistic regression analysis, the ADC ratio was an independent significant differentiator of SKIT from LKIT. The AUROC of ADC ratios was 0.816 ± 0.07. The optimal cut-off value for the identification of LKIT was 1.25 × 10−3 (sensitivity 96.3%, specificity 62.5%). Conclusion MRI features may identify the overbroad scope of G2 PNETs and help predict Ki-67 values, as a surrogate for tumor aggressiveness, in G2 PNETs. An optimal cut-off value for predicting Ki-67 status (≥/< 5%) was 1.25 × 10−3 of ADC ratio.

  • Principles of three-dimensional printing and clinical applications within
           the abdomen and pelvis
    • Authors: Sarah Bastawrous; Nicole Wake; Dmitry Levin; Beth Ripley
      Abstract: Improvements in technology and reduction in costs have led to widespread interest in three-dimensional (3D) printing. 3D-printed anatomical models contribute to personalized medicine, surgical planning, and education across medical specialties, and these models are rapidly changing the landscape of clinical practice. A physical object that can be held in one’s hands allows for significant advantages over standard two-dimensional (2D) or even 3D computer-based virtual models. Radiologists have the potential to play a significant role as consultants and educators across all specialties by providing 3D-printed models that enhance clinical care. This article reviews the basics of 3D printing, including how models are created from imaging data, clinical applications of 3D printing within the abdomen and pelvis, implications for education and training, limitations, and future directions.

      Abstract: Purpose Radiological evaluation of the efficacy of preoperative chemotherapy for colorectal liver metastasis (CRLM) is the most important tool for determining treatment strategies. The aim of this study was to identify a correlation between morphologic appearance on computed tomography (CT) and histologic findings of CRLM after preoperative chemotherapy. Methods We examined 47 patients who had undergone a first hepatic resection for CRLM after preoperative chemotherapy and had received contrast-enhanced CT scans. We assessed the morphologic appearance of the overall attenuation based on metastases changing from heterogeneous to mixed and homogenous lesions, the tumor–liver interface, and the peripheral rim enhancement on CT. Histologic parameters included usual necrosis (UN), infarct-like necrosis (ILN), three-zonal change, dangerous halo, mucous lake, shape of ILN, dominant type of necrosis, and presence of viable tumor cells. The relationship between morphologic appearance and histologic findings was evaluated. Results CT overall attenuation revealed that UN predominance was more common in the heterogeneous group than in the mixed and homogeneous groups (P = 0.011). The frequency of ILN increased sequentially from ill-defined to variable and sharp at the tumor–liver interface (P = 0.038), and the frequency of UN decreased sequentially from present to partially resolved and completely resolved in the peripheral rim enhancement (P = 0.023). The histologic presence of viable tumor cells was closely associated with the tumor–liver interface (P = 0.0003) and the peripheral rim enhancement (P = 0.004). Conclusions CT morphologic appearance of CRLM after preoperative chemotherapy is correlated with histologic findings regarding necrosis.
