      Purpose The study sought to examine the association between clinical image quality of mammograms and screening sensitivity. Methods Four radiologists evaluated the clinical image quality of 374 invasive screen-detected cancers and 356 invasive interval breast cancers for which quality evaluation of screening mammograms could be assessed from cancers diagnosed among participants in the Quebec Breast Cancer Screening Program in 2007. Quality evaluation was based on the Canadian Association of Radiologists accreditation criteria, which are similar to those of the American College of Radiology. The association between clinical quality and screening sensitivity was assessed by logistic regression. Adjusted sensitivity and adjusted sensitivity ratios were obtained through marginal standardization. No institutional review board approval was required. Results A proportion of 28% (206 of 730) of screening mammograms had lower overall quality for the majority of assessments. Positioning was the quality attribute that was the most frequently deficient. The 2-year screening sensitivity reached 68%. Sensitivity of screening was not statistically associated with the overall quality (ratio of 2-year sensitivity = 1.03; 95% confidence interval: 0.93-1.15) or with any quality attributes (positioning, exposure, compression, sharpness, artifacts, contrast). Results were similar for the 1-year sensitivity. Conclusions Although not all mammograms in the Quebec screening program met the optimum quality required by the Canadian Association of Radiologists or American College of Radiology accreditation, the screening mammograms produced in this population-based organized screening program reached a high enough level of quality so that the remaining variation in quality is too little to impair screening sensitivity.

      Hepatopancreaticobiliary tumours are often diagnosed at an advanced disease stage, in which encasement or invasion of local biliary or vascular structures has already occurred. Irreversible electroporation (IRE) is an image-guided tumour ablation technique that induces cell death by exposing the tumour to high-voltage electrical pulses. The cellular membrane is disrupted, while sparing the extracellular matrix of critical tubular structures. The preservation of tissue integrity makes IRE an attractive treatment option for tumours in the vicinity of vital structures such as splanchnic blood vessels and major bile ducts. This article reviews current data and discusses future trends of IRE for hepatopancreaticobiliary tumours.

      Liver tumour ablation nowadays represents a routine treatment option for patients with primary and secondary liver tumours. Radiofrequency ablation and microwave ablation are the most widely adopted methods, although novel techniques, such as irreversible electroporation, are quickly working their way up. The percutaneous approach is rapidly gaining popularity because of its minimally invasive character, low complication rate, good efficacy rate, and repeatability. However, matched to partial hepatectomy and open ablations, the issue of ablation site recurrences remains unresolved and necessitates further improvement. For percutaneous liver tumour ablation, several real-time imaging modalities are available to improve tumour visibility, detect surrounding critical structures, guide applicators, monitor treatment effect, and, if necessary, adapt or repeat energy delivery. Known predictors for success are tumour size, location, lesion conspicuity, tumour-free margin, and operator experience. The implementation of reliable endpoints to assess treatment efficacy allows for completion-procedures, either within the same session or within a couple of weeks after the procedure. Although the effect on overall survival may be trivial, (local) progression-free survival will indisputably improve with the implementation of reliable endpoints. This article reviews the available needle navigation techniques, evaluates potential treatment endpoints, and proposes an algorithm for quality control after the procedure.

      The atrioventricular (AV) groove constitutes the anatomic space separating the atria and ventricles. The AV groove is often difficult to visualize at echocardiography, and suspected lesions can be further assessed with cardiac computed tomography or magnetic resonance imaging. AV groove lesions may originate from within the AV groove or extend into this space from adjacent structures. The differential diagnosis for AV groove lesions is often wide, but a precise diagnosis can sometimes be made. This pictorial essay illustrates the magnetic resonance imaging and computed tomography appearance of common and uncommon AV groove lesions, and attempts to provide a logical framework for differential diagnosis when confronted with a known or suspected lesion at cross-sectional imaging.

      Artificial intelligence (AI) is rapidly moving from an experimental phase to an implementation phase in many fields, including medicine. The combination of improved availability of large datasets, increasing computing power, and advances in learning algorithms has created major performance breakthroughs in the development of AI applications. In the last 5 years, AI techniques known as deep learning have delivered rapidly improving performance in image recognition, caption generation, and speech recognition. Radiology, in particular, is a prime candidate for early adoption of these techniques. It is anticipated that the implementation of AI in radiology over the next decade will significantly improve the quality, value, and depth of radiology's contribution to patient care and population health, and will revolutionize radiologists' workflows. The Canadian Association of Radiologists (CAR) is the national voice of radiology committed to promoting the highest standards in patient-centered imaging, lifelong learning, and research. The CAR has created an AI working group with the mandate to discuss and deliberate on practice, policy, and patient care issues related to the introduction and implementation of AI in imaging. This white paper provides recommendations for the CAR derived from deliberations between members of the AI working group. This white paper on AI in radiology will inform CAR members and policymakers on key terminology, educational needs of members, research and development, partnerships, potential clinical applications, implementation, structure and governance, role of radiologists, and potential impact of AI on radiology in Canada.

      Objectives The percutaneous endovascular abdominal aortic repair (PEVAR) approach is a minimally invasive technique that has demonstrated clinical benefit over traditional surgical cut down associated with standard endovascular abdominal aortic aneurysm (AAA) repair (EVAR). The objective of our study was to evaluate the budget impact to a Canadian hospital of changing the technique for AAA repair from the EVAR approach to the PEVAR approach. Methods We examined the budget impact of replacing the EVAR approach with the PEVAR approach in a Canadian hospital that performs 100 endovascular AAA repairs annually. The model incorporates the costs associated with surgery, length of stay, and postoperative complications occurring within 30 days. Results The use of PEVAR in AAA repair is associated with increased access device costs when compared with the EVAR approach (CAD$1000 vs CAD$400). However, AAA repair completed with the PEVAR approach demonstrates reduced operating time (101 minutes vs 133 minutes), length of stay (2.2 days vs 3.5 days), time in the recovery room (174 minutes vs 193 minutes), and postoperative complications (6% vs 30%), which offset the increased device costs. The model establishes that switching to the PEVAR approach in a Canadian hospital performing 100 AAA repairs annually would result in a potential cost avoidance of CAD$245,120. Conclusions A change in AAA repair technique from EVAR to PEVAR can be a cost-effective solution for Canadian hospitals.

      Laparoscopic sleeve gastrectomy is one of the most common bariatric procedures worldwide. It has recently gained in popularity because of a low complication rate, satisfactory resolution of comorbidities, and excellent weight loss outcome. This article reviews the surgical technique, expected postsurgical imaging appearance, and imaging findings of common complications after laparoscopic sleeve gastrectomy. Understanding of the surgical technique of laparoscopic sleeve gastrectomy and of the normal postsurgical anatomy allows accurate interpretation of imaging findings in cases of insufficient weight loss, weight regain, and postsurgical complications.

      Purpose To explore the patient perception on radiation-related cancer risk from interventional radiology (IR) procedures and whether informed radiation consent is warranted. Methods A multiple-choice survey was prospectively administered to 68 adults undergoing a body or neuro-IR procedure with ionizing radiation exposure. Subgroup analysis with chi-square or Fisher exact test was performed based on patient past IR history (P < .05). Results A total of 81% of patients wanted to be informed if there was a radiation-related 3% increased cancer risk over 5 years. Although 55% considered 3% a small risk, 28% wanted to further discuss the risks and alternate options, and 15% would have only proceeded if it were a life-saving procedure: 89%, 80%, and 67% of patients wanted to be informed with exposure risks of 1 in 100, 1 in 1000, and 1 in 10,000, respectively. Only 53% were aware they were going to be exposed to radiation, irrespective of past IR history (P = .15). Most patients believed radiation consent should include radiation-related cancer risks (85%). No past IR history was significantly associated with wanting consent to include cancer-related risk (100% vs 76%; P = .01) and deterministic risks (70% vs 41%; P = .04). A majority (69%) believed both the referring physician and the interventional radiologist were responsible for obtaining radiation consent, and 65% of patients wanted verbal consent followed by signed written consent, regardless of past IR history. Conclusions Many patients want to discuss cancer-related radiation risks with both radiologists and physicians. Informed radiation consent should be considered for procedures with high anticipated radiation doses.

      This review presents a summary of the pathology and epidemiology of Modic changes and the possible role of Propionibacterium acnes. This information is followed by a synthesis of the most recent clinical research involved in culturing the discs of patients with degenerative disc disease for the presence of bacteria. We also discuss a randomized controlled trial that investigates the effects of antibiotics on patients with chronic low back pain and type 1 Modic changes. We conclude with a brief discussion of the difficulties involved in this research and the significance of the findings.

      This pictorial essay demonstrates the variable appearances of ductal carcinoma in situ on full-field digital mammography, synthesized mammography, and digital breast tomosynthesis. The spectrum of intercase and intracase variability suggests further refinement of reconstruction algorithms for synthesized mammography may be necessary to maximize early detection of ductal carcinoma in situ.

      Ankle impingement syndromes are a commonly encountered clinical entity seen in athletes, secondary to repetitive forceful microtrauma. Symptoms are related to impingement of osseous or soft tissue abnormalities in the ankle joint, in particular the tibiotalar joint, which may result in painful limitation of ankle movements. Imaging modalities, such as radiographs and magnetic resonance imaging, are very useful in diagnosing osseous and soft tissue abnormalities seen in different types of ankle impingement syndromes. This article reviews the classification of ankle impingement syndromes, their etiology, and clinical and radiological findings.

      Purpose In the management of thyroid nodules, although the potential for malignancy exists, there is also the potential for overtreatment of subclinical disease. Although the TI-RADS (Thyroid Imaging-Reporting and Data System) system outlines a risk stratification score based on suspicious ultrasound findings, it has not been universally accepted. Many TI-RADS 2 or 3 patients proceed to fine needle aspiration biopsy (FNAB), potentially unnecessarily. The aim of the study was to identify whether lesions within a multinodular goiter (MNG) without suspicious features can be followed with ultrasound rather than biopsied as is recommended for single nodules. Methods Pathology records were retrospectively analysed for proven MNGs over a 5-year period. A total of 293 cases were identified. FNAB, prebiopsy ultrasound images, and reports were identified for each case. Images were reviewed and assessed for sonographically suspicious criteria guided by TI-RADS. Logistic regression was applied to determine if any sonographic features were associated with neoplasia. Odds ratios with 95% confidence intervals were calculated. Results Of 293 samples, 14 (4.7%) were neoplastic. Having no suspicious features conferred an average risk of 0.0339 (95% confidence interval: 0.02831-0.04087) of neoplasia. Risk of neoplasm significantly increased by having 1 and >1 suspicious feature (P < .001). Regarding cytological results, of 237 patients with Thy-2 cytology, 159 were followed up and 8 had a neoplasm. Conclusion Ultrasound can be used to estimate risk of neoplasia in MNG. In the absence of suspicious radiological findings, follow-up with ultrasound rather than FNAB may be appropriate in patients who have a low clinical suspicion for neoplasia.

      Purpose The objective of the study was to evaluate the performance of magnetic resonance imaging (MRI) for the diagnosis of appendicitis during pregnancy. Methods We conducted a retrospective review of all MRI scans performed at our institution, between 2006 and 2012, for the evaluation of suspected appendicitis in pregnant women. Details of the MRI scans performed were obtained from the radiology information system as well as details of any ultrasounds carried out for the same indication. Clinical and pathological data were obtained by retrospective chart review. Results The study population comprised 63 patients, and 8 patients underwent a second MRI scan during the same pregnancy. A total of 71 MRI scans were reviewed. The appendix was identified on 40 scans (56.3%). Sensitivity of MRI was 75% and specificity was 100% for the diagnosis of appendicitis in pregnant women. When cases with right lower quadrant inflammatory fat stranding or focal fluid, without appendix visualization, were classified as positive for appendicitis, MRI sensitivity increased to 81.3% but specificity decreased to 96.4%. Conclusions MRI is sensitive and highly specific for the diagnosis of appendicitis during pregnancy and should be considered as a first line imaging study for this clinical presentation.

      Purpose The study sought to prospectively evaluate which technique among T2-weighted images, dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI), diffusion-weighted (DW) MRI, or a combination of the 2, is best suited for prostate cancer detection and local staging. Methods Twenty-seven consecutive patients with biopsy-proven adenocarcinoma of the prostate underwent MRI on a 1.5T scanner with a surface phased-array coil prior radical prostatectomy. Combined anatomical and functional imaging was performed with the use of T2-weighted sequences, DCE MRI, and DW MRI. We compared the imaging results with whole mount histopathology. Results For the multiparametric approach, significantly higher sensitivity values, that is, 53% (95% confidence interval [CI]: 41.0-64.1) were obtained as compared with each modality alone or any combination of the 3 modalities (P < .05). The specificity for this multiparametric approach, being 90.3% (95% CI: 86.3-93.3) was not significantly higher (P < .05) as compared with the values of the combination of T2+DCE MRI, DW+DCE MRI, or DCE MRI alone. Among the 3 techniques, DCE had the best performance for tumour detection in both the peripheral and the transition zone. High negative predictive value rates (>86%) were obtained for both tumour detection and local staging. Conclusions The combination of T2-weighted sequences, DCE MRI, and DW MRI yields higher diagnostic performance for tumour detection and local staging than can any of these techniques alone or even any combination of them.

      Background Vascular compression of the anterior optic pathway has been documented as an infrequent cause of visual impairments. Here we characterize such vascular compression using magnetic resonance imaging. Methods A total of 183 patients without pathologies affecting the optic pathways underwent T2-weighted or constructive interference steady-state sequence magnetic resonance imaging. Imaging data from coronal sections were analyzed. Results A vascular compression of the anterior optic pathway was identified in 20 patients (11%). They comprised 13 men and 7 women with a mean age of 60.8 years. The vascular compressions were observed at 22 sites, 15 on the optic nerve (ON) and 7 on the optic chiasm (OC). Twelve of them were on the right and 10 were on the left side. The offending vessels were the supraclinoid portion of the internal carotid artery in 86.4% and the A1 segment of the anterior cerebral artery in 13.6%. Compression sites at the ON and OC were variable, with the inferolateral surface being the most frequent (77.3% occurrences). In 2 patients (9.1%), the ON was compressed in a sandwich manner. Conclusions Vascular compression of the ON and OC may not be an infrequent occurrence in the cranial cavity. Progressive and unexplainable visual impairment might possibly be caused by vascular-compressive neuropathy.

      Purpose The study sought to determine Canadian radiology resident perception of and interest in global health imaging (GHI) and the barriers they encounter in pursuing GHI experiences during residency training. Methods A peer-reviewed, online, anonymous, multiple-choice survey was distributed to Canadian radiology residents at English-language programs. Results Fifty residents responded to the survey (∼16% response rate); 72% of respondents perceived an unmet need for medical imaging in the developing world. A majority of residents (60%) would have been likely to participate in a GHI experience if one had been available during their residency; 65% planned on pursuing international outreach work as future radiologists, 81% of whom with on-site collaboration in education and training of local staff. However, 82% of respondents were uncertain or believed they would not be adequately prepared to help improve access and availability of medical imaging services in developing countries upon completion of residency. Overall, residents believed a GHI program would increase their knowledge of infectious diseases, increase their exposure to diseases at advanced stage presentation, enhance their knowledge of basic imaging modalities, and improve their cultural competence. Lack of information about opportunities, lack of funding, and lack of infrastructure were ranked as the most important barriers to participating in a radiology rotation in a developing country during residency. Conclusion While many Canadian radiology residents are interested in participating in GHI, their preparation to do so may be inadequate. Formalizing international GHI rotations may alleviate barriers impeding their pursuit.

      There is a wide spectrum of congenital anomalies of the superior vena cava, which are more increasingly recognized in cross-sectional imaging. Although some of these anomalies are asymptomatic, others have important clinical and interventional implications. Imaging modalities such as computed tomography and magnetic resonance imaging play an important role in the accurate characterization of these anomalies, which is essential for mapping prior to surgeries or interventions. In this article, we review a wide range of anomalies of the superior vena cava, including the embryological basis, cross-sectional imaging findings, and clinical implications, particularly from an interventional radiology perspective. We also discuss the treatments and complications of these anomalies.

      Purpose Technological advancements and the ever-increasing use of computed tomography (CT) have greatly increased the detection of incidental findings, including tiny pulmonary nodules. The management of many “incidentalomas” is significantly influenced by a patient's history of cancer. The study aim is to determine if CT requisitions include prior history of malignancy. Methods Requisitions for chest CTs performed at our adult tertiary care hospital during April 2012 were compared to a cancer history questionnaire, administered to patients at the time of CT scan. Patients were excluded from the study if the patient questionnaire was incomplete or if the purpose of the CT was for cancer staging or cancer follow-up. Results A total of 569 CTs of the chest were performed. Of the 327 patients that met inclusion criteria, 79 reported a history of cancer. After excluding patients for whom a history of malignancy could not be confirmed through a chart review and excluding nonmelanoma skin cancer, dysplasia, and in situ neoplasm, 68 patients were identified as having a history of malignancy. We found 44% (95% confidence interval [0.32-0.57]) of the chest CT requisitions for these 68 patients did not include the patient's history of cancer. Of the malignancies that were identified by patient questionnaire but omitted from the clinical history provided on the requisitions, 47% were malignancies that commonly metastasize to the lung. Conclusions A significant number of requisitions failed to disclose a history of cancer. Without knowledge of prior malignancy, radiologists cannot comply with current guidelines regarding the reporting and management of incidental findings.

      An environmental-friendly radiology department should be a requirement of the future era. The aim of this article is to make radiologists aware of their responsibilities for a greener world. We have suggested a number of minor but important changes in various sections of a radiology department that can make the radiology department more environmentally friendly. These small steps require relatively little effort on our part but cumulatively, may have a huge positive impact on our environment.
