Modern low-field MRI (<1T) now yields diagnostic-quality neuroimages, enabled by AI reconstruction and improved gradient design. Reduced susceptibility artifact aids skull base and implant imaging, while portability permits point-of-care scanning. However, high-field MRI remains…
New ACG guideline: CT essential for first/severe diverticulitis diagnosis. Against routine antibiotics in low-risk uncomplicated cases. Colonoscopy after complicated or in uncomplicated with alarm symptoms to rule out malignancy.
AI-based biopsy sparing for BI-RADS 4A+ breast lesions can be translated into clinically actionable decision-making, suggests a new study in J Ultrasound Med.
In 1245 adults, nnU-Net automated 3D segmentation of eye and orbit on T1 MRI was accurate, yielding biomarkers like axial length and volume. First large-scale unbiased atlases (female, male) created for MR-eye standardization.
Electron density from dual-energy CT correlates with hemoglobin levels—AUC up to 0.96 for anemia detection on non-contrast CT. Even on contrast-enhanced CT, ED remained associated (AUC 0.73–0.90) while conventional attenuation did not, suggesting opportunistic screening potentia…
An automated AI pipeline, externally validated on 2,448 fundus photos, classified optic disc tilt with a clinical acceptance rate >98%. The tool detected tilt in 7.5% of images overall and 9.7% of normal eyes, but performance dropped for images with edema, with acceptance as low…
In 703 NICM pts, myocardial Gremlin-1 overexpression on biopsy was independently tied to higher all-cause and CV mortality, and ICD events over 15y. It improved risk prediction.
Lipid droplets promote spontaneous liquid-liquid phase separation of wild-type and E46K mutant α-synuclein. These condensates impair lipid droplet turnover and disrupt mitochondrial function, suggesting a mechanism for neurodegeneration in Parkinson’s disease.
OLFGO, a new fungal growth optimizer with orthogonal learning, ranked first for lung CT segmentation in a 20-image test vs. existing methods (exact metrics not reported).
Physician evaluations of LLM responses on real clinical cases showed substantial heterogeneity by seniority and setting, shifting model rankings. AI agents provided efficient but insufficiently nuanced assessments, unable to replace human judgment.
BoneCoT AI improved AUC for distinguishing primary vs metastatic bone lesions by 40% over radiologists (multi-center, 10 hospitals), with 20% AUC gain over prior methods across 26 tasks. Trained on 29.3M CT images.
Vascular calcification in lower extremity PAD impairs diagnostic accuracy, complicates endovascular therapy, and predicts poor outcomes. This review finds current imaging limited by inconsistent scoring, with AI-assisted quantification and molecular imaging needed for improvemen…
Flow Matching (FM) augmentation of thyroid scintigraphy data led to the highest classifier F1-scores (macro 0.77) and AUC (macro 0.93). FM-generated images were most realistic (FID 0.66), outperforming Stable Diffusion and conventional augmentation on a multi-center dataset of 2…
This educational video from AJNR presents a pattern-based CT approach to osseous trauma at the craniocervical junction, helping radiology residents and early-career neuroradiologists recognize occipital condyle, atlas, odontoid, and axis fractures through multiplanar imaging and…
Systemic medical therapy for vascular anomalies can reduce pain, bleeding, and the need for repeat procedures, complementing embolization and sclerotherapy. This narrative review summarizes current agents, indications, dosing, and monitoring considerations to optimize multidisci…
Less invasive perinatal postmortem exams (PMMR with laparoscopic sampling, molecular testing, AI) can provide diagnostic yield when autopsy is declined, but imaging alone misses microscopic pathology.
In early-stage ALS, structural–functional coupling is significantly reduced in the somatomotor network (pFDR=0.001), while structural connectivity appears preserved. The decoupling correlates spatially with 5-HT2A/mGluR5 receptors and a microglial gene signature, notably FMN1 do…
