The ACR has issued its 2026 update to Appropriateness Criteria for myelopathy, providing evidence-based imaging guidance for acute, chronic, and vascular causes of spinal cord dysfunction to help differentiate extrinsic from intrinsic pathology.
In 82,957 women with negative screening mammograms (Kaiser Permanente cohort), combining Mirai AI, a 313-SNP polygenic score, and BCSCv3 clinical risk reached C-index 0.70 (95% CI 0.69–0.71) vs 0.66, 0.62, and 0.61 for each alone — supporting integrated risk-stratified screening.
After venous sinus stenting for pulsatile tinnitus, temporal bone remodeling occurred in 73.1% of patients with follow-up CT (38/52). Remodeling was significantly more likely with a diverticulum vs isolated wall dehiscence (85.7% vs 47.1%; adjusted OR 8.08, 95% CI 1.31-49.73), a…
Across >3 million multicenter emergency department encounters, overall ED neuroimaging utilization doubled from 2016 to 2025. Head CT without contrast remained dominant, but CT perfusion use rose >5-fold over the same period, signaling a marked shift in acute stroke workup inten…
At ESSR, radiologists competed on MSK Hero, a pattern-recognition game. True speed came from instant recognition, not overthinking—a reminder that visual calibration can be tested and trained. (No formal study; anecdotal challenge.)
After venous sinus stenting for pulsatile tinnitus, temporal bone remodeling occurred in 73.1% of patients with follow-up CT (38/52). Remodeling was significantly more likely with a diverticulum vs isolated wall dehiscence (85.7% vs 47.1%; adjusted OR 8.08, 95% CI 1.31-49.73), a…
In PSC, gadoxetate MRI REPD <4.64 predicted 2-year adverse events (sens 70%, spec 63%), adding independent value beyond Mayo Risk Score in a retrospective cohort (n=73).
In a multi-ethnic cohort, midlife hypertension (OR 4.02) and smoking (OR 4.94) were strongly associated with carotid plaque calcifications on 3T MRI; smoking also linked to lipid-rich necrotic core (OR 2.88). Intraplaque hemorrhage rare (3.9%).
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.
Adding a 3D VIBE sequence to T1/STIR MRI in children with suspected juvenile spondyloarthritis boosted reader confidence (consensus sensitivity 38.5%, specificity 94.8%) but did not significantly improve diagnostic accuracy.
Review argues that the 'black box' nature of many prostate MRI AI tools hinders trust and clinical adoption. Explainable AI (XAI) techniques and standardized reporting frameworks are needed to shift to informed decision-making, but robust external validation in real-world cohort…
Interviews with 10 Canadian IM faculty revealed that transgender health—even evidence-based areas like cardiovascular care—is excluded from residency curricula. A Queer Theory lens identified an unspoken 'default patient' as cisgender, with structural forces (hierarchy-driven de…
据AuntMinnie报道，一项调查显示介入放射科医生群体在关键议题上形成了超级多数（supermajority），表明观点高度一致。具体议题和数字尚未披露。
Diagnostic Imaging will showcase highlighted interviews from the SNMMI 2026 Annual Meeting, providing coverage of breaking research and expert perspectives in nuclear medicine and molecular imaging.
Emergency department neuroimaging use increased by 45% over the last ten years, rising far faster than ED visit volumes, raising downstream concerns around incidental findings, length of stay, and cost without proportional changes in acuity.
In RSNA Unscripted, Tessa Cook, MD, PhD, argues that radiology must cut through generative AI hype and refocus on tangible patient impact. She also discusses maintaining core values and persuading leadership when environments don't align.
An AuntMinnie MinnieCast episode reviews where ABUS (automated breast ultrasound) stands today, discussing clinical adoption, evidence gaps for dense breasts, and its place relative to handheld ultrasound and mammography. No new data are reported.
The FDA has cleared new functionalities for DeepHealth’s AI-powered breast imaging suite. (Exact features not disclosed in the announcement.)
An AI-powered brain tumor segmentation tool has been cleared by the FDA, marking a key step for the manufacturer's expansion into North America. The clearance covers automated tumor delineation on imaging; specific performance metrics or predicate device details were not disclos…
A new independent report from Signify Research examines why Voice AI pilots for specialty patient access stall, available free. Published via PR Newswire and Artera, the report highlights adoption barriers without offering quantitative data.
The American College of Radiology has launched a new login portal for the Journal of the American College of Radiology (JACR), transitioning authentication to jacr-auth.acr.org. The change affects how members access journal content; members should update bookmarks and login cred…
The American College of Radiology (ACR) has released a summary outlining how the Medicare Payment Advisory Commission's (MedPAC) June 2026 report could affect radiology reimbursement and practice, though exact financial figures are not yet publicly available.
ACR Chief Research Officer Dr. Etta Pisano highlighted the College's AI initiatives and strengthened international collaborations, underscoring radiology's role in shaping artificial intelligence in medicine.
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…
Integrated phenotyping of 69 patients with idiopathic pleuroparenchymal fibroelastosis (PPFE) using quantitative CT and clinical markers identified two reproducible clusters. The severe fibrotic phenotype carried an 8.6-fold higher mortality risk (95%CI 1.06-70.4). A four-variab…
In 258 dental exam questions, AI models varied: Gemini led factual recall (p=0.048), but no model excelled in analytical reasoning (p=0.032). AI aids education, not yet reliable for clinical decisions in oral radiology.
