ASFNR clinical state-of-practice: For posterior circulation large vessel occlusion stroke, use noncontrast CT to exclude hemorrhage, CT angiography to identify occlusion, and MRI with DWI as reference standard. Imaging scores like PC-ASPECTS help select patients for thrombectomy.
The ACR Appropriateness Criteria 2026 update provides imaging guidelines for suspected or confirmed diffuse lung disease, covering initial evaluation, acute exacerbation, and surveillance.
New expert consensus framework for symptomatic B3 breast lesions: assess concordance, lower excision threshold for discordant/palpable lesions, conservative management for concordant non-atypical lesions, and risk-based surveillance for atypia.
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…
Internally validated multimodal CT radiomics and inflammatory marker model achieved AUC 0.931 (sensitivity 0.957, specificity 0.782) for preoperative parotid mass risk stratification in 490 patients. Exploratory: AUC 0.952 vs MSRSGC 0.712.
In weight-stable adults, weight cyclers had greater thigh muscle volume loss on MRI over 48 months (−3.71% vs −1.03%, P=.003) than noncyclers, with no difference in intermuscular adipose tissue or knee subcutaneous fat changes.
PE-RADS v2026 introduces a standard lexicon and structured reporting for CT/MR angiography in acute PE, categorizing clot location and right heart features to determine cardiovascular status and guide management.
Real-world Lessons for AI in Breast Cancer Screening: One Size Does Not Fit All.
General radiologists' cancer detection rate rose from 3.76 to 4.99 per 1000 exams (P<.001) with an AI workflow, matching specialists' 4.76/1000 (P=.53). Recall PPV improved (3.38% to 3.89%, P=.02).
Exposure parameters cause shortcut learning in radiography deep learning models.
An AI decision support system (NeurAneuNet) achieved 95.2% agreement with expert consensus for Pipeline Embolization Device sizing in an independent cohort of 21 intracranial aneurysms, and reduced clinician planning time by 44.8%.
More than Meets the Eye: Exposure Parameters Cause Shortcut Learning in Radiography Deep Learning Models.
An automated segmentation model (FCN-ResNet-50) identified 14 foot and ankle bones on AP and oblique radiographs with a mean intersection over union (mIoU) of 0.899–0.975 and 6 bones on lateral views with mIoU of 0.926–0.976, slightly outperforming DeepLabv3.
An AI chatbot showed diagnostic accuracy comparable to three fellowship-trained orthopedic trauma surgeons for determining surgery in isolated lateral malleolar fractures. AUC values were similar for the AI and all surgeons (0.63–0.67). All raters, including the AI, recommended…
Plain Radiographs, Smarter Triage: Deep Learning and Clinical Context in Bone Tumor Assessment.
Erratum for: Ten-year Longitudinal Relationship between Spinal Degenerative Lesions in Axial Spondyloarthritis at MRI and Radiography in the DESIR Cohort.
Erratum for: 61Cu-NODAGA Prostate-specific Membrane Antigen Imaging and Therapy for Prostate Cancer: Phase 1 Trial of a New Class of 61Cu-labeled PET Radiotracers.
Entropy Refines Risk in Acute Myocarditis: An Early Career Perspective.
Orbital subperiosteal and epidural hematomas can occur secondary to sickle cell bone infarcts, as shown in a 6-year-old boy with progressive eye swelling. Contrast-enhanced CT and MRI help make the diagnosis.
When Electrons Cooperate with Photons: Prostate Cancer Loses Its Sanctuary.
In women at high breast cancer risk, CEM incidence screens had higher specificity (91.5% vs 83.4%) and accuracy (91.4% vs 83.5%) than prevalence screens, with similar cancer detection rates (11.6 vs 19 per 1000).
Beyond the First Screen: Building the Case for Contrast-enhanced Mammography as a Sustainable Screening Strategy.
In 1388 adults with type 2 diabetes, a cardiac MRI-based risk model (SCAN-MRI) achieved an AUC of 0.76 for predicting heart failure hospitalization or cardiovascular death, significantly better than existing clinical risk scores (AUC 0.66 and 0.65, both P<.001).
Muscle-involving Polyarteritis Nodosa.
Phenotype over Probability: Cardiac MRI Risk Stratification in Type 2 Diabetes Mellitus.
ISGE updates its endometriosis dynamic ultrasound structured report: new template adds superficial peritoneal descriptors, lateral compartment subdivision (parametrium, pelvic sidewall, nerves), and quantitative pelvic metrics to improve completeness and surgical concordance.
Siemens Healthineers' Mammomat B.brilliant Gains FDA Clearance for Enhanced Imaging and Biopsy
PET/CT guides treatment in men with recurrent prostate cancer
FDA cleared Siemens Healthineers' Mammomat B.brilliant mammography system, offering enhanced imaging and biopsy capabilities.
FDA recall warns of a server glitch that can cause radiologists to read and report on the wrong patient's images during interactive applications. The defect may lead to patient misidentification.
FDA cleared a breast imaging system with contrast-enhanced mammography (CEM) and biopsy capabilities, broadening access to CEM as clinical evidence supporting its use grows.
