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…

Takeaways from the ACR-RBMA Practice Leadership Forum
Curium is in advanced talks to buy Lantheus for $7 billion, potentially combining two major players in diagnostic radiopharmaceuticals such as the PET tracer Pylarify. No final decision has been reached.
ACR projects CT angiography of the chest (CPT 71275) will increase 149% to $83.09 under the proposed 2027 Medicare fee schedule, while other codes like CT upper extremity without dye face cuts (-15%). The conversion factor drops 1.68% to $32.84.
Siemens Healthineers and Vanderbilt Health announced an $87M multi-year partnership to standardize imaging and radiation oncology equipment, integrate AI, and support workforce development across Nashville-based sites.
In a study of 540 adults, six calcaneal angles measured on radiographs were not suitable for sex prediction. Key angles like Böhler and Gissane varied with age, while calcaneal compression differed between sexes. These population-specific reference values may aid clinical diagno…
An automated MRI-based AI framework staged pubertal olecranon bone age with internal accuracies of 94.12% (girls) and 93.75% (boys); external validation at a second centre achieved 86.67% (girls) and 90.48% (boys), with mean absolute errors of 0.233 and 0.095 years.
Artificial intelligence for interstitial lung disease pattern recognition on high-resolution computed tomography: A step forward for general radiologists.
A combined prospective and retrospective motion-correction approach (SAMER) for 2D TSE MRI reduced normalized root mean squared error in 90% of moderate-to-severe motion cases and significantly decreased overall reconstruction error across 274 simulated clinical inpatient trajec…
Long-term PM2.5 and PM10 exposure correlated with higher pericoronary fat attenuation index on CCTA: each IQR increase in PM2.5 raised right coronary artery FAI by 7.57 HU. Associations strongest in hypertension, diabetes, and smokers.
Artificial intelligence in radiology.
In a retrospective study of 120 patients, electrocautery tract closure after percutaneous core needle biopsy resulted in no major bleeding, transfusions, or procedure-related deaths at 30 days, with four small intraprocedural hematomas that did not progress.
A letter in World Journal of Radiology warns deep learning models for spontaneous ICH may mistake basal ganglia calcifications for hematoma heterogeneity and chronic lacunar infarcts for perihematomal edema, inflating false positives. Radiologist-verified quantitative radiomics…
A nomogram based on smoking, metabolic status, BMI, age, and sex predicts cardiopulmonary abnormalities on LDCT with AUC 0.833 (95% CI 0.787-0.879) in validation, outperforming age/sex alone (AUC 0.647).
Combining CT radiomics with alpha-fetoprotein and total bilirubin yielded an AUC of 0.948 for predicting glypican-3 expression in hepatocellular carcinoma, up from 0.862 with radiomics alone.
3D-printed anatomical models developed from medical imaging data were rated positively for usability and learning support in gross anatomy education, offering a complementary resource when cadaver access is limited.
