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…
This lecture explains the ITMIG mediastinal classification, dividing the mediastinum into prevascular, visceral, and paravertebral compartments. It details the anatomical boundaries of each compartment and demonstrates how a compartment-based approach can narrow the differential…
New Eurorad teaching case demonstrates the distinctive neuroradiological features of ACTA2 mutations, which cause smooth muscle dysfunction syndrome with characteristic brain MRI findings.
Midwest Radiology added 33 radiologists in 2026. Its recruiting director outlines the strategies behind the unusually large hiring class — a rare operational look at large-group physician recruitment in radiology.
AIRS Medical, developer of the SwiftMR deep-learning MRI acceleration platform, has received private equity investment. The 2018-founded firm claims SwiftMR reduces scan times while improving image quality; deal terms were not disclosed.
FDA cleared E-Scopics' hepatoscope, a quantitative ultrasound device. It combines transient elastography for fibrosis, attenuation imaging for steatosis, and B-mode for morphology in one exam, intended for point-of-care liver assessment.
FDA issues warning letter to Zoll Medical over safety lapses with its MRI-compatible ventilators, alerting clinicians to potential hazards during scanning. Details of the lapses were not specified in the brief trade report.
RSNA's portfolio of journals achieved significant impact factor increases, with 'Radiology' rising to 19.7 and 'RadioGraphics' to 6.5, solidifying their positions as top-tier resources in medical imaging. Other journals also saw double-digit percentage gains.
Metallic and "cat-eye" nail polishes containing ferromagnetic particles can heat up and cause significant artifacts during MRI, posing a potential burn risk. In testing, some formulations showed temperature increases exceeding 2°C (exact figure not reported in source).
Expert commentary from Michael Hofman summarizes key molecular imaging themes from the 2026 SNMMI annual meeting. Specific findings and data not reported in source; full details require access to the original interview.

OBJECTIVES: To evaluate short-term pain relief and safety provided by polidocanol foam sclerotherapy for painful venous malformations (VMs) and determine imaging and procedural predictors of clinical efficacy. MATERIALS AND METHODS: From April 2015 to September 2025, this sing...
OBJECTIVES: MRI can reveal the signal characteristics and invasive potential of tumors. Our study aimed to explore the potential of MRI-identified primary tumor aggressiveness-related factors in nasopharyngeal carcinoma (NPC). MATERIALS AND METHODS: This study retrospectively...
OBJECTIVES: Computed tomography (CT) scans for lung cancer screening provide the opportunity of quantifying incidental findings. We evaluated the repeatability of AI-based measurements of incidental findings using short-term repeat CT scan pairs. MATERIALS AND METHODS: AI-Rad...
PURPOSE: To investigate the effects of vendor-neutral image-domain deep learning reconstruction (DLR) applied retrospectively to dynamic contrast-enhanced (DCE) images from prostate multiparametric magnetic resonance imaging (MRI) on image quality and diagnostic performance fo...
