ACR Appropriateness Criteria for indolent lung cancer: For patients with slow-growing subsolid nodules or atypical cysts where surveillance is chosen over intervention, imaging follow-up aims to detect changes that alter management, with modality selection guided by accuracy and…
0.55T lung MRI detected consolidations with 86% sensitivity in sarcoidosis, but only 27-29% for reticulations and traction bronchiectasis. Functional MRI added ventilation and perfusion defect measures that correlated with PFT (e.g. VDP vs RV/TLC r=0.90). Radiation-free.

A logistic regression model predicted 28-day all-cause mortality in ICU patients with cirrhosis and esophagogastric varices with AUROC 0.882 (95% CI 0.795–0.924) in external validation, with the white cell-platelet ratio z-score as a strong determinant.
AI accurately classified 3 major interstitial lung disease patterns on HRCT (77.8% accuracy vs thoracic experts’ median 75.6%). For radiology residents, AI assistance improved accuracy by 14.8% and cut reading time by 20.7% (P<0.001), but 6/8 residents still performed worse than…
TACE-induced liver injury spans transient lab changes to post-TACE liver failure, but definitions vary widely, hampering study comparisons. Gut microbiota and NLRP3 inflammasome pathways may improve risk prediction.
A decade of AI hype, fueled by replacement narratives, has not supplanted radiologists. Evidence now shows AI's real value in narrow, well-defined tasks like triage and workflow optimization, while its limitations—including hallucinations and narrow clinical relevance—temper the…
A novel feed-forward ML model (GUSL) matched or exceeded deep-learning performance for prostate gland segmentation on MRI, with a Dice score >0.9 across multiple datasets. Its interpretable, regression-based design avoids backpropagation and has a much smaller model size.
ESTRO-ASTRO consensus: (chemo)reirradiation for locally recurrent rectal cancer can increase radical resection rate and improve control, but recommendations rely on low-quality evidence and expert consensus. Careful patient selection and precision techniques essential.
The General Attitudes toward Artificial Intelligence Scale (GAAIS), Attitudes toward Ethical AI Scale (AT-EAI), and AI Anxiety Scale (AIAS) showed good factorial validity and reliability in 705 Albanian students/staff (CFI≥0.987). Exploratory analyses: affective AI anxiety most…
A review outlines rational design, directed evolution, and AI-based methods to engineer AAV gene therapy vectors with improved cross-species translatability, addressing receptor binding, trafficking, immunity, and toxicity barriers.
In a scoping review of 70 sources (2015-2026), informed consent for AI was endorsed in 95.7% (67/70) but formal protocols were proposed in only 8.6% (6/70). Most evidence was conceptual, with dynamic consent uncommon (8.6%), underscoring the need for practical, risk-adapted AI c…
Retrospective Italian dental study: admission test score <40/90 linked to 5-fold higher odds of not completing first-year credits (OR 5.04, 95% CI 3.18–7.98) and double the odds of delayed graduation (OR 2.27).
RGCNN-nnUNet achieved Dice scores of 0.885 (white matter) and 0.86 (deep gray matter) on multi-center NCCT. When its tissue-specific Z-score maps were combined with AI-denoised CT, a blinded reader study showed a 29% increase in diagnostic sensitivity for stroke compared with st…
Longitudinal change in deep learning-based effusion-synovitis volume (ΔESV) over 48 months was associated with concurrent knee OA progression (p<0.001). ΔESV showed stronger associations for ΔKL grade than semiquantitative MOAKS (ΔIDD=0.22, p=0.002).
AI-based radiomics on 18F-FDG PET/CT improves distinction between benign and metastatic mediastinal nodes in non-small cell lung cancer. Models combining radiomic features with clinical and conventional PET metrics consistently outperformed radiomics-only approaches. Performance…
