BackgroundFewer residents are choosing a career in pediatric radiology, which is contributing to an ongoing shortage of pediatric radiologists.ObjectiveTo identify potential causes of reduced interest in pediatric radiology as a career given a projected worsening of a nationwide shortage of pediatric radiologists.Materials and methodsAn online questionnaire using previously published questions was approved and distributed by the Program Directors in Diagnostic Radiology to diagnostic radiology residents on behalf of the Society for Pediatric Radiology (SPR). Descriptive statistics including means with standard error and independent t-tests were used to compare mean scores between survey years.ResultsNearly all of the 353 respondents (90.9%) planned on pursuing a fellowship. The majority (57.7%) identified their fellowship subspecialty before the 3rd year of residency with only 5.7% selecting pediatric radiology. Overall, 18.2% of survey respondents favored academic practice compared to 40% in the pediatric radiology subgroup. Fellowship choices were most strongly based on area of strong personal interest, marketability and area of strong personal knowledge, while the pediatric radiology subgroup emphasized area of strong personal interest, increased interaction with other physicians and enjoyable residency rotations. The pediatric radiology subgroup believed their impact on patient care was more significant than other subspecialties. Pediatric radiology job opportunities were thought to be more limited, geographically confining, and to have lower salaries than other subspecialties. More flexible job opportunities and higher demand were identified as factors needing to change before a resident would consider a pediatric radiology career.ConclusionThe influence on fellowship selection is multifactorial. By emphasizing the favorable job market and marketability of pediatric radiology in all practice types/geographic locations, correcting perceived salary gaps and stressing the impact on patient care as early as medical school, the number of residents choosing a career in pediatric radiology may grow.

The ability of computed tomography (CT) to distinguish between benign congenital lung malformations and malignant cystic pleuropulmonary blastomas (PPBs) is unclear. To assess whether chest CT can detect malignant tumors among postnatally detected lung lesions in children. This retrospective multicenter case-control study used a consortium database of 521 pathologically confirmed primary lung lesions from January 1, 2009, through December 31, 2015, to assess diagnostic accuracy. Preoperative CT scans of children with cystic PPB (cases) were selected and age-matched with CT scans from patients with postnatally detected congenital lung malformations (controls). Statistical analysis was performed from January 18 to September 6, 2020. Preoperative CT scans were interpreted independently by 9 experienced pediatric radiologists in a blinded fashion and analyzed from January 24, 2019, to September 6, 2020. Accuracy, sensitivity, and specificity of CT in correctly identifying children with malignant tumors. Among 477 CT scans identified (282 boys [59%]; median age at CT, 3.6 months [IQR, 1.2-7.2 months]; median age at resection, 6.9 months [IQR, 4.2-12.8 months]), 40 cases were extensively reviewed; 9 cases (23%) had pathologically confirmed cystic PPB. The median age at CT was 7.3 months (IQR, 2.9-22.4 months), and median age at resection was 8.7 months (IQR, 5.0-24.4 months). The sensitivity of CT for detecting PPB was 58%, and the specificity was 83%. High suspicion for malignancy correlated with PPB pathology (odds ratio, 13.5; 95% CI, 2.7-67.3; P = .002). There was poor interrater reliability (κ = 0.36 [range, 0.06-0.64]; P < .001) and no significant difference in specific imaging characteristics between PPB and benign cystic lesions. The overall accuracy rate for distinguishing benign vs malignant lesions was 81%. This study suggests that chest CT, the current criterion standard imaging modality to assess the lung parenchyma, may not accurately and reliably distinguish PPB from benign congenital lung malformations in children. In any cystic lung lesion without a prenatal diagnosis, operative management to confirm pathologic diagnosis is warranted.
