  • Deep learning of birth-related infant clavicle fractures: a potential
           virtual consultant for fracture dating

    • Free pre-print version: Loading...

      Abstract: Background In infant abuse investigations, dating of skeletal injuries from radiographs is desirable to reach a clear timeline of traumatic events. Prior studies have used infant birth-related clavicle fractures as a surrogate to develop a framework for dating of abuse-related fractures. Objective To develop and train a deep learning algorithm that can accurately date infant birth-related clavicle fractures. Materials and methods We modified a deep learning model initially designed for face-age estimation to date infant clavicle fractures. We conducted a computerized search of imaging reports and other medical records at a tertiary children’s hospital to identify radiographs of birth-related clavicle fracture in infants ≤ 3 months old (July 2003 to March 2021). We used the resultant database for model training, validation and testing. We evaluated the performance of the deep learning model via a four-fold cross-validation procedure, and calculated accuracy metrics: mean absolute error (MAE), root mean square error (RMSE), intraclass correlation coefficient (ICC) and cumulative score. Results The curated database consisted of 416 clavicle radiographs from 213 infants. Average chronological age (equivalent to fracture age) at time of imaging was 24 days. This model estimated the ages of the clavicle fractures with MAE of 4.2 days, RMSE of 6.3 days and ICC of 0.919. On average, 83.7% of the fracture age estimates were accurate to within 7 days of the ground truth. Conclusion Our deep learning study provides encouraging results for radiographic dating of infant clavicle fractures. With further development and validation, this model might serve as a virtual consultant to radiologists estimating fracture ages in cases of suspected infant abuse.

  • Lung and large airway imaging: magnetic resonance imaging versus computed
           tomography

    • Free pre-print version: Loading...

      Abstract: Abstract Disorders of the respiratory system are common in children and imaging plays an important role for initial diagnosis and follow-up evaluation. Radiographs are typically the first-line imaging test for respiratory symptoms in children and, when advanced imaging is required, CT has been the most frequently used imaging modality. However, because of increasing concern about potentially harmful effects of ionizing radiation on children, there has been a shift toward MRI in pediatric imaging. Although MRI of chest in children presents many technical challenges, recent advances in MRI technology are overcoming many of these issues, and MRI is now being used for evaluating the lung and large airway in children at centers with expertise in pediatric chest MRI. In this article we review the state of pediatric lung and large airway imaging, with an emphasis on cross-sectional modalities and the roles of MRI versus CT.

  • Ultrasound findings of acute pancreatitis in children

    • Free pre-print version: Loading...

      Abstract: Background Studies systematically documenting US findings in children with acute pancreatitis are limited. Pancreas duct dilation is described as the most reliable finding of acute pancreatitis but this has not been rigorously examined in children. Objective To systematically document US findings in children with acute pancreatitis and to define interobserver agreement on those findings. Materials and methods In this cross-sectional study we retrospectively reviewed images for all pediatric patients <18 years of age who had been prospectively enrolled in a registry of patients with index admissions for acute pancreatitis between March 2013 and July 2020. Two blinded observers (R1, R2) reviewed the first transabdominal US examination performed within 2 weeks of the pancreatitis attack for each patient. Results In 141 children, US was performed at a median of 1 day (interquartile range [IQR]: 0, 1) following acute attack. Thirty-three (23%, R1) and 38 (27%, R2) children had no abnormal findings on US. Peripancreatic edema was the most frequent finding documented by both reviewers (63% R1, 54% R2). The pancreatic duct was visible in only 35% of the children and was dilated in only 12% (R1) and 14% (R2). There was substantial to almost-perfect agreement between reviewers on findings of acute pancreatitis (κ=0.62–1), including duct visibility. Conclusion Peripancreatic edema was the most frequently identified finding in children with acute pancreatitis, present in up to 63%, with almost perfect interobserver agreement. Duct dilation, cited in the literature as a reliable finding of acute pancreatitis, was rarely identified in our sample.

  • Quantitative cardiopulmonary magnetic resonance imaging in
           neonatal congenital diaphragmatic hernia

    • Free pre-print version: Loading...

      Abstract: Background Pulmonary arterial hypertension, impaired cardiac function and lung hypoplasia are common in infants with congenital diaphragmatic hernia (CDH) and are associated with increased morbidity and mortality. Robust noninvasive methods to quantify these abnormalities in early infancy are lacking. Objective To determine the feasibility of MRI to quantify cardiopulmonary hemodynamics and function in infants with CDH and to investigate left–right blood flow and lung volume discrepancies. Materials and methods We conducted a prospective MRI study of 23 neonates (isolated left CDH: 4 pre-repair, 7 post-repair, 3 pre- and post-repair; and 9 controls) performed on a small-footprint 1.5-tesla (T) scanner. We calculated MRI-based pulmonary arterial blood flow, left ventricular eccentricity index, cardiac function and lung volume. Using the Wilcoxon rank sum test for continuous data and Fisher exact test for categorical data, we made pairwise group comparisons. Results The right-to-left ratios for pulmonary artery blood flow and lung volume were elevated in pre-repair and post-repair CDH versus controls (flow: P<0.005; volume: P<0.05 pre−/post-repair). Eccentricity index at end-systole significantly differed between pre-repair and post-repair CDH (P<0.01) and between pre-repair CDH and controls (P<0.001). Conclusion Cardiopulmonary MRI is a viable method to serially evaluate cardiopulmonary hemodynamics and function in critically ill infants and is useful for capturing left–right asymmetries in pulmonary blood flow and lung volume.

  • Disorders of phosphate homeostasis in children, part 2: hypophosphatemic
           and hyperphosphatemic disorders

    • Free pre-print version: Loading...

      Abstract: Abstract Phosphorus, predominantly in the form of inorganic phosphate PO4−3, has many essential physiological functions. In the skeleton, phosphate and calcium form the mineral component and phosphate is also essential in regulating function of skeletal cells. Considerable advances have been made in our understanding of phosphate homeostasis since the recognition of fibroblast growth factor-23 (FGF23) as a bone-derived phosphaturic hormone. This second part of a two-part review of disorders of phosphate homeostasis in children covers hypophosphatemic and hyperphosphatemic disorders that are of interest to the pediatric radiologist, emphasizing, but not limited to, those related to abnormalities of FGF23 signaling.

  • Disorders of phosphate homeostasis in children, part 1: primer on mineral
           ion homeostasis and the roles of phosphate in skeletal biology

    • Free pre-print version: Loading...

      Abstract: Abstract Phosphate has extensive physiological roles including energy metabolism, genetic function, signal transduction and membrane integrity. Regarding the skeleton, not only do phosphate and calcium form the mineral component of the skeleton, but phosphate is also essential in regulating function of skeletal cells. Although our understanding of phosphate homeostasis has lagged behind and remains less than that for calcium, considerable advances have been made since the recognition of fibroblast growth factor-23 (FGF23) as a bone-derived phosphaturic hormone that is a major regulator of phosphate homeostasis. In this two-part review of disorders of phosphate homeostasis in children, part 1 covers the basics of mineral ion homeostasis and the roles of phosphate in skeletal biology. Part 1 includes phosphate-related disorders of mineralization for which overall circulating mineral ion homeostasis remains normal. Part 2 covers hypophosphatemic and hyperphosphatemic disorders, emphasizing, but not limited to, those related to increased and decreased FGF23 signaling, respectively.

  • Pediatric large airway imaging: evolution and revolution

    • Free pre-print version: Loading...

      Abstract: Abstract Infants and children often present with respiratory symptoms referable to the airway. For these pediatric patients, airway imaging is frequently performed to evaluate for underlying disorders of the large airway. Various imaging modalities have been used to evaluate the pediatric large airway, and pediatric airway imaging techniques have continued to evolve. Therefore, clear understanding of the status and new advances in pediatric large airway imaging is essential for practicing radiologists to make timely and accurate diagnoses, which can lead to optimal pediatric patient management.

  • Prevalence of inflicted and neglectful femur shaft fractures in young
           children in national level I trauma centers

    • Free pre-print version: Loading...

      Abstract: Background The prevalence of inflicted femur fractures in young children varies (1.5–35.2%), but these data are based on small retrospective studies with high heterogeneity. Age and mobility of the child seem to be indicators of inflicted trauma. Objective This study describes other factors associated with inflicted and neglectful trauma that can be used to distinguish inflicted and neglectful from accidental femur fractures. Materials and methods This retrospective study included children (0–6 years) who presented with an isolated femur fracture at 1 of the 11 level I trauma centers in the Netherlands between January 2010 and January 2016. Outcomes were classified based on the conclusions of the Child Abuse and Neglect teams or the court. Cases in which conclusions were unavailable and there was no clear accidental cause were reviewed by an expert panel. Results The study included 328 children; 295 (89.9%) cases were classified as accidental trauma. Inflicted trauma was found in 14 (4.3%), while 19 (5.8%) were cases of neglect. Indicators of inflicted trauma were age 0–5 months (29%, positive likelihood ratio [LR +] 8.35), 6–12 months (18%, LR + 5.98) and 18–23 months (14%, LR + 3.74). Indicators of neglect were age 6–11 months (18%, LR + 4.41) and age 18–23 months (8%, LR + 1.65). There was no difference in fracture morphology among groups. Conclusion It is unlikely that an isolated femur fracture in ambulatory children age > 24 months is caused by inflicted trauma/neglect. Caution is advised in children younger than 24 months because that age is the main factor associated with inflicted trauma/neglect and inflicted femur fractures.

      Abstract: Abstract Applications for bowel US in children have been well described; however, less focus has been placed on patterns of bowel wall architectural change in specific disease states. This pictorial essay reviews normal bowel wall architecture and covers a variety of inflammatory, infectious, vascular and neoplastic disorders outside the neonatal period as seen on US, with illustrative pathological correlation. A thorough understanding of normal and abnormal bowel wall architecture can enrich sonographic interpretation and provide a valuable adjunct to appropriate clinical investigation.

  • Diagnostic accuracy of ultrasound for localising peripherally inserted
           central catheter tips in infants in the neonatal intensive care unit: a
           systematic review and meta-analysis

    • Free pre-print version: Loading...

      Abstract: Background Chest radiography after peripherally inserted central catheter insertion in infants is the reference standard method for verifying catheter tip position. The utilisation of ultrasound (US) for catheter placement confirmation in the neonatal and paediatric population has been the focus of many recent studies. Objective In this systematic review we investigated the diagnostic accuracy of US for peripherally inserted central catheter tip confirmation in infants in the neonatal intensive care unit (NICU) Materials and methods We conducted a systematic literature search of multiple databases. The study selection yielded eight articles, all of which had acceptable quality and homogeneity for inclusion in the meta-analysis. Sensitivity and specificity values were reported together with their respective 95% confidence intervals (CI). Results After synthesising the eligible studies, we found that US had a sensitivity of 95.2% (95% CI 91.9–97.4%) and specificity of 71.4% (95% CI 59.4–81.6%) for confirming catheter tip position. Conclusion Analyses indicated that US is an excellent imaging test for localising catheter tip position in the NICU when compared to radiography. Ultrasonography is a sensitive, specific and timely imaging modality for confirming PICC tip position. In cases where US is unable to locate malpositioned PICC tips, a chest or combined chest–abdominal radiograph should be performed.

  • Density map estimation with convolutional neural networks to count
           radiopaque markers on colonic transit studies

    • Free pre-print version: Loading...

      Abstract: Background A radiopaque marker study measures colonic transit time for work-up of primary constipation. It requires the patient to ingest multiple tiny radiopaque markers, which the radiologist must count manually on follow-up abdominal radiographs. Counting these markers is tedious but cognitively simple. Objective To develop a convolutional neural network (CNN) capable of counting the number of radiopaque markers on abdominal radiographs. Materials and methods The image archive at a large tertiary children’s hospital was searched to identify abdominal radiographs performed in children for the indication of a radiopaque marker study. To establish the ground truth, a radiologist manually labeled the coordinates of the radiopaque markers in each radiograph and thereby generated a density map for that radiograph. A CNN was trained to estimate this density map from its corresponding abdominal radiograph. Spatially integrating the output density map provided an estimate of the number of markers in the radiograph. To assess model accuracy, mean absolute error and root mean square error were calculated. Results The study cohort consisted of 436 radiographs (mean number of markers per radiograph: 34). This cohort was randomly divided into training, validation and testing sets consisting of 306, 65 and 65 radiographs, respectively. Based on the testing set, the CNN accurately estimated the number of markers in each radiograph with mean absolute error=2.6 markers and root mean square error=3.9 markers. Conclusion The proposed CNN generated promising results in counting the number of radiopaque markers on abdominal radiographs and offers the potential of automating the interpretation of colonic transit studies.

  • Childhood interstitial lung disease more prevalent in infancy: a practical
           review

    • Free pre-print version: Loading...

      Abstract: Abstract Childhood interstitial lung disease (chILD) is a heterogeneous group of uncommon, mostly chronic pediatric pulmonary disorders characterized by impaired gas exchange and diffuse abnormalities on imaging. A subset of these diseases occurs more frequently in infants and young children than in older children and teenagers. Some of these disorders occur in certain clinical scenarios and/or have typical imaging features that can help the radiologist recognize when to suggest a possible diagnosis and potentially spare a child a lung biopsy. We review the clinical, histopathological and computed tomography features of chILD more prevalent in infancy, including diffuse developmental disorders, growth abnormalities, specific conditions of undefined etiology, and surfactant dysfunction mutations and related disorders, to familiarize the pediatric radiologist with this group of disorders.
