On MRI, LI-RADS LR-5 had higher PPV for HCC than KLCA-NCC definite HCC (93.9% vs 91.7%, p<0.001); on CT, PPVs were equal (92.9%). Corresponding probability categories should not be used interchangeably.
In a 100-question radiology MCQ test, Gemini 2.5 Pro achieved 90% accuracy, with Claude 4.5 Sonnet at 86%. All LLMs and 3rd-year residents outperformed juniors. No performance gap between Turkish and English (P=1.000). Claude showed best temporal reliability (κ=0.872).
In a 92-patient prospective STEMI cohort, an AI-driven coronary CTA model predicted 1-year MACE (AUC 0.876) significantly better than the GRACE score (AUC 0.742, p=0.012). Key predictors included total plaque volume >400 mm3, low-attenuation plaque, and LV end-diastolic volume c…
An AI system detected clavicle fractures on AP radiographs with 95.8% sensitivity, 98.9% specificity, and AUC 0.95—performance comparable to an experienced orthopedic surgeon in a single-center retrospective study of 367 exams. Second-plane view results were similarly high.
A Random Forest model using obesity composite indices achieved an AUC of 0.895 (0.864–0.926) for identifying kidney stone history in patients with both diabetes and hypertension. Roundness fat mass and lipid accumulation product were the strongest predictors. Validation was on a…
CT-based radiomics with an SVM classifier predicted high PD-L1 expression (≥50%) in NSCLC with AUC 0.83 (IQR 0.63-0.92) in a small retrospective study of 55 patients. Clinical data did not improve performance; texture features were most informative. Not yet externally validated.
Preoperative cone-beam breast CT (CE-CBBCT) radiomics predicted high Ki-67 in breast cancer (AUC 0.885 at 14% cut-off; 0.831 at 30% cut-off, external test cohort). Adding deep learning did not significantly improve performance. The radiomics score for Ki-67 ≥30% independently pr…
