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…
RadNet Experiences Significant Growth in Advanced Imaging Procedures
A consortium of 12 U.S. hospital systems aims to build AI workflows for radiology to speed interpretation and improve outcomes, with data sharing across ~20M patients/yr. First results 2027.

3D MRE: More Precise for Measuring Liver Stiffness in Adults with Severe Obesity
Nanox.AI Enhances Medical Imaging with Intel's OpenVINO
In a single-center survey of 10 IR attendings, a night-float call system increased sleep (6 vs 5.5 hrs), was preferred by 60%, and reduced wRVUs per FTE by 6% compared to traditional 24-hour call.
Solis Mammography opened 4 new centers in Colorado, North Carolina, and Florida, offering 3D mammography and AI services including Mammo+Heart for breast arterial calcification. The company now operates over 170 locations.
The best diagnosis is in this patient with cough and fever.
A narrative review finds that global radiology remains dominated by short-term outreach models, neglecting the systems issues—workforce, equipment maintenance, financing, and governance—required for sustainable, equitable imaging services.
Letter to the Editor: "Energy consumption of standard and contrast-enhanced mammography: a step towards sustainable breast imaging".
Women with preeclampsia had significantly higher susceptibility in temporal cingulum (left: 15.75 vs 9.95 ppb; right: 14.86 vs 8.48 ppb) and left fornix (5.07 vs 1.14 ppb) on quantitative susceptibility mapping (QSM) MRI compared with pregnant controls in a cohort of 350 women.
Brain age gap was 3.5 years in type 1 diabetes, rising to 6-7 years with peripheral neuropathy, per MRI-based deep learning. Diabetes duration drove brain aging, while neuropathic pain had no clear contribution.
ASTRO guideline for pancreatic cancer: RT recommended preop for borderline resectable, definitive for locally advanced; conditionally for resectable. Preop: conventional/moderate hypofractionation; postop: conventional; definitive: dose-escalated SBRT. Palliative RT for symptoms.
In a meta-analysis of 6 studies, robot-assisted neuroendovascular procedures had longer operating room time (mean difference 12.42 min, 95% CI 6.31–18.53) but lower contrast volume (MD –6.20 ml, 95% CI –11.91 to –0.50). Procedure and fluoroscopy times, diagnostic success, and co…
Neuroradiologists showed only fair interrater agreement (mean κ=0.22) when interpreting MRIs from 14 operatively confirmed Cushing disease patients with indeterminate findings. All agreed that a system to convey imaging certainty in reports would be helpful.
Combining abnormal craniocervical junction (CCJ) CT measurements, fracture, and hemorrhage yields high diagnostic accuracy (AUC 0.86-0.91) for pediatric CCJ ligamentous injury, with sensitivity up to 96% and specificity 95%.
Primitive basal vein of Rosenthal (BVR) drainage (type 3) was more frequent in PMNSAH than controls (47.4% vs 24.4%), but BVR variants did not predict hemorrhage severity or neurological outcome. Age was independently associated with worse outcomes.
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.
An AI algorithm for CTA detected anterior circulation large vessel occlusions with 95.8% sensitivity and 88.6% specificity. In a multicenter study of 379 patients, mean time-to-notification was just 3.30 minutes, supporting its use as a rapid triage tool.
7T MRI more than doubles venous cerebral microbleed (vCMB) detection in CAA vs 3T (1173 vs 385), with higher vCMB ratio (0.70 vs 0.33). But weak cross-scanner correlation (r=0.32) precludes interchangeability; 7T may better detect small lesions.
Conservative management predominated (94%) in 573 renal trauma patients. Embolization achieved 100% technical success, nephrectomy rate 3%. 30-day all-cause mortality 2.3%, renal-specific 0.2%.
For 100 kVp ultra-low-dose chest CT, a machine learning phantom-less QCT model reduced bone mineral density error vs standard 120 kVp model (2.39 vs 16.68 mg/cm³, p<0.0001) and agreed with DXA in 88.8%.
Why AI struggles with rare catastrophic disease: lessons from the AORTA-AI study of acute aortic syndrome.
A narrative review finds deep learning models, including CNNs and GANs, can segment and classify lumbar spine radiographs, with lightweight architectures potentially deployable in resource-limited environments. However, real-world validation and clinical integration challenges p…
A multimodal signature combining CT radiomics, deep learning, and pathomics achieved a C-index of 0.821 for progression-free survival prediction in chondrosarcoma, outperforming individual signatures (validation cohort).
A radiomics-based support vector machine (SVM) model using parotid ultrasound distinguished Sjögren's disease from healthy controls with AUC 0.99, accuracy 0.94, sensitivity 0.86, specificity 0.96, outperforming radiologists' accuracy of 0.62–0.72.
A hierarchical deep learning model on X-rays detected acute osteoporotic vertebral fractures with 91% sensitivity (95% CI 84.8-95.0%) and 98.8% NPV.
UAB startup LifeNuclear is developing TheraGuide, a digital platform to replace complex paper-based radiation safety instructions with interactive checklists, multilingual support, and personalized timelines after radiopharmaceutical therapy.
