AI assessment of mandibular canal–third molar relationship on CBCT/panoramic radiography achieves accuracy 80–97%, AUC 0.84–0.98 across 29 studies; however, lack of external validation limits clinical deployment.
Domain-specific AI (M4CXR) showed 55.8% complete concordance vs 19.8% for ChatGPT-4o on 500 CXRs, and cut reporting time from 179s to 16s (P<.001). Retrospective single-center; findings suggest specialized AI improves consistency.
In 923 adolescents, vertebral body fractal dimension (FD) on cephalograms added only 0.6% accuracy (77.8% vs 77.2%) for classifying skeletal growth phases versus age and sex alone. Chronological age and sex remained the primary predictors.
In 114 adults with mild TBI and ICH, 22.8% later deteriorated. Midline shift (OR 11.6), SBP ≥160 mmHg (OR 5.5), multiple ICHs (OR 3.7), and GCS 13–14 (OR 4.9) independently predicted need for admission or neurosurgery. Retrospective single-center data.
A CT-based AI model predicted macrotrabecular-massive HCC with an AUC of 0.845 in external validation, and identified patients with worse survival on immunotherapy (all P<0.05).
Combined AI-assisted and expert-led teaching improved radiology residents' diagnostic scores for pulmonary nodules on CT more than either alone, a small RCT found. Post-test theoretical: 91.8 vs 82.6 (P<0.001); practical: 93.5 vs 81.9. Higher confidence at 1 month.
In a retrospective study, a combined MRI radiomics+2.5D deep learning model predicted early complete response to chemoimmunotherapy in nasopharyngeal cancer with an external test AUC of 0.821, sensitivity 0.859, and NPV 0.932.
Retrospective multicenter study: In 674 pts >70y with EVT, frailty (CFS>3) was independently associated with lower 90d functional independence (aOR 13.45, 95% CI 2.57-70.3). Random forest AUROC 0.82; frailty top feature. External validation needed.
Single-center study of 55 men with PI-RADS 3+1 lesions (upgraded by DCE) found clinically significant prostate cancer (csPCa) in 29% (16/55). 71% of biopsies were negative for csPCa. Results support individualized decision-making rather than automatic PI-RADS 4 management. PSA d…
In an RCT of 40 patients after ACL reconstruction, adding contralateral-limb balance training improved gait speed (0.08 m/s, 95% CI 0.05-0.11) and sagittal knee ROM (8.97°, 95% CI 5.40-12.54), but clinical significance uncertain.
A cross-sectional audit of 507 clinical images from UCSD preclinical dermatology/rheumatology materials found light/white skin in 60%, medium/brown in 29%, and dark/black in only 11% (χ²=186.26, p<0.001), with underrepresentation across all disease categories. Findings highlight…
In a survey of 82 UK radiographer reporting programme alumni, 97.6% went on to report after qualification, but only 89% were currently reporting due to mobility into management and leadership roles. Most worked as advanced practitioners (50%) at NHS band 7 (70%).
In a nationwide survey of 200 medical imaging students and practitioners, 62.5% reported AI was incorporated into their curriculum, yet only 44% had received direct instruction on AI, revealing a gap between curriculum presence and practical training.
Adding MRI-based synthetic CT to MRI and X-ray improved radiologists' assessment quality for cervical radiculopathy (median score 3.8 vs 3.2, p<0.001); trabecular bone visibility unchanged. Single-centre exploratory study with 24 patients.
In a multicenter reader study, adding deep learning to breast MRI interpretation raised radiologists' precision for subcentimeter (≤1 cm) invasive cancers from 72.9% to 83.2% without a significant change in sensitivity (89.5% vs 86.8%, p>0.05).
The American College of Radiology (ACR) is emphasizing inter-society and multidisciplinary collaboration as a strategic priority to address radiology's biggest challenges. This shift focuses on uniting voices across the field rather than any single clinical finding (specific met…
