- * The results showed that both groups had similar levels of competence, but specialists were better at identifying subtle cases, and there were no significant differences in error rates based on time of day.
- * Findings indicated a notable number of missed and overcalled cases, underlining the importance of double readings and improved training in radiology, particularly in certain musculoskeletal regions with lower sensitivity and specificity.
Joint effusion due to elbow fractures are common among adults and children. Radiography is the most commonly used imaging procedure to diagnose elbow injuries. The purpose of the study was to investigate the diagnostic accuracy of deep convolutional neural network algorithms in joint effusion classification in pediatric and adult elbow radiographs.

Methods: Men with newly diagnosed unfavourable intermediate- or high-risk PCa prospectively underwent F-PSMA-1007 PET/CT, WBMRI with DWI and contrast-enhanced CT within a median of 8 days. Six readers (two for each modality) independently reported pelvic lymph nodes as malignant, equivocal or benign while blinded to the other imaging modalities.
Background: Computed tomography (CT) and bone scintigraphy (BS) are the imaging modalities currently used for distant metastasis staging of prostate cancer (PCa).
Objective: To compare standard staging modalities with newer and potentially more accurate imaging modalities.
Design, Setting, And Participants: This prospective, single-centre trial (NCT03537391) enrolled 80 patients with newly diagnosed high-risk PCa (International Society of Urological Pathology grade group ≥3 and/or prostate-specific antigen [PSA] ≥20 and/or cT ≥ T3; March 2018-June 2019) to undergo primary metastasis staging with two standard and three advanced imaging modalities.
