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…

Impact of CTA Timing on Outcomes in Blunt Cerebrovascular Injuries
Northside Radiology Associates, a Radiology Partners affiliate with 70+ physicians, signs a multi-year in-network agreement with Anthem BCBS of Georgia, ensuring continued in-network access to diagnostic and interventional imaging for members.
ACR released a handout helping patients understand AI-generated radiology report summaries, advising they discuss unclear results with their radiologist or provider. The resource aims to improve patient understanding and can be incorporated into workflows.
Imaging turnaround times continued to climb in 2024
Photon-counting CT is comparable with MR elastography for liver fibrosis.
PET imaging reveals tau pathology in 65% and amyloid in 35% of patients with psychosis beginning after age 40, vs 15% and 2% in controls, suggesting neurodegenerative disease drives these symptoms.
A new multidisciplinary clinical educator team across a large medical imaging network boosted self-reported confidence in first-trimester communication, from 2.7 to 3.5 on a 4-point scale, and increased education reach. Early results support the workforce model.
An automated AI TAVR planner showed excellent agreement with semi-automated software for aortic annulus area (ICC 0.976, 95% CI 0.966-0.984) and reduced planning time from 9.55 to 1.03 minutes per case (p=0.001).
BI-RADS v2025 brings mammographic density alignment with Mammography Quality Standards Act, nonmass lesions on ultrasound, revised MRI enhancing lesion terminology, and first dedicated contrast-enhanced mammography section, harmonizing lexicon across modalities.
An MRI radiomics model predicted loss of photoreceptorness (a tumor differentiation marker) in retinoblastoma with an AUC of 0.81 in an independent testing cohort, providing a potential non-invasive biomarker for a cancer where biopsy is contraindicated.

In rural Nigeria, 33% of 9,585 AI-screened chest X-rays were abnormal. TB was confirmed in 204 people (95% started treatment), but among the 2,367 with suspected chronic respiratory or cardiovascular disease, only 12% completed the referral.
A new commentary proposes a six-part framework and 90-day roadmap to shift radiology AI from fragmented point solutions to a managed operational capability with shared governance, integration, and measurement.
Combined radiomics-clinical model from baseline CT predicted PFS in HR+/HER2- advanced breast cancer on CDK4/6 inhibitor + endocrine therapy (C-index 0.85 training, 0.76 testing) but requires external validation.
Combining T1 contrast-enhanced and T2-weighted MRI radiomics with habitat analysis achieved AUC 0.863 (95% CI 0.763-0.954) for meningioma subtyping, outperforming radiomics-only and habitat-only models.
Advances in detector technology, quantitative PET/SPECT, patient-specific dosimetry, and AI are transforming pediatric nuclear medicine from standardized activity administration toward personalized radiation dose optimization, maximizing diagnostic and therapeutic benefit while…
Synthetic contrast-enhanced CT from a GAN improved gastric cancer histologic grade prediction AUC by 5.9% (internal) and 0.7% (external) over non-contrast CT in a 1,757-patient multicenter study. Lauren classification prediction improved 6.8% and 7.3%.
