LLMs tested on 93 mixed dentition radiographs for tooth ID, caries, and periapical assessment

Large language models evaluated on 93 mixed dentition radiographs from children: Gemini 3 Pro had highest accuracy for tooth identification and caries detection, but none could identify periodontitis. All LLMs were inferior to expert human judgment.

Chain-of-thought prompting improves AI detection of radiology report errors across seven LLMs

RadCoT, radiologist-style chain-of-thought prompting, lifted mean error-detection F1 from 0.77 to 0.85 (p=0.003) across seven LLMs on 1,200 reports. GPT-4o hit F1 0.93; open-source Llama-3.3-70B reached 0.89, close to commercial standard prompting.

CT morphometrics and AI show promise for complex ventral hernia repair but lack robust validation

CT morphometrics (loss of domain, muscle quality) and AI (automated segmentation, radiomics) show promise for predicting outcomes in ventral hernia repair, but evidence is limited to small retrospective studies without external validation.

Adult BI-RADS risk estimates overstate cancer risk in pediatric breast masses

In 279 excised breast lesions in patients under 20, none were malignant and 87% were fibroadenomas, yet 55% were Breast Imaging Reporting and Data System (BI-RADS) 4—adult estimates overpredict pediatric cancer risk.

Radiology Training Needs 'AI-Conscious' Teaching, Not Prohibition

Radiology trainees are using generative AI for clinical and study tasks, but limited institutional guidance risks data bias and cognitive deskilling. A panel advocates embedding 'AI-conscious' teaching instead of prohibitive policies.
