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…
Accessory Cavitated Uterine Mass.
CT first-line for early prostate post-procedure complications (hemorrhage, collections); fluoroscopy for urinary leaks/fistulas/strictures; MRI (+PSMA PET) for late complications & recurrence. Knowing expected vs unexpected findings avoids delayed diagnosis.
This RadioGraphics review details how advanced neuroimaging is crucial for planning and guiding high-intensity focused ultrasound, laser interstitial thermal therapy, and deep brain stimulation treatments for movement disorders and epilepsy.
This dermatologic primer helps breast radiologists evaluate common skin abnormalities by integrating clinical and imaging findings to guide biopsy decisions.

Radiology Board Examinations: A Fundamental Shift.
A knowledge-distilled diffusion model with meta-guidance improved cone-beam CT image quality, achieving MAE 13.22 HU, SSIM 0.9516, and PSNR 30.35 dB, significantly outperforming baselines (p<0.01).
A logistic regression model using MRI and amyloid PET features classified tau positivity in amyloid-positive cohorts with AUC 0.92, accuracy 85%, sensitivity 83%, specificity 85% on external validation. MCI subjects with predicted tau positivity progressed to AD faster (p<10^-6).
Mixed Reality-Assisted Planning Enables Successful Coil Embolization of Anatomically Complex Peridevice Leak After LAAC.
3D radiomic texture analysis of quantitative muscle MRI reveals distinct fat infiltration patterns: higher entropy and contrast in Charcot-Marie-Tooth type 1A vs myotonic dystrophy type 1, reflecting reticular vs confluent fat replacement. CMT1A also showed steeper disto-proxima…
Editorial. The unspoken curriculum: grief across the arc of a neurosurgical career.
In 105 children with perinatal stroke, brain age prediction from T1 MRI showed accelerated aging (more positive brain age gaps) versus matched controls, especially in arterial ischemic stroke. Motor scores negatively correlated with brain age gaps, with sex-specific differences.
A deep learning algorithm (XProstate) for prostate cancer MRI detection performed similarly to radiologists in external validation: heat map AUC 0.76 (0.70-0.82) vs PI-RADS 0.73 (0.68-0.79), p=0.38. 202 patients, MR-US fusion biopsy gold standard.
AI synthetic CT from MR showed soft-tissue HU differences <50 HU and centroid shifts <2 mm vs reference CT in brain and prostate RT, but bone HU compression reached 347±14 HU in femoral heads.
A radiomics-deep learning nomogram using planar whole-body bone scintigraphy predicted MDP-avid bone metastases in non-small cell lung cancer with an external validation AUC of 0.870 (95% CI 0.840-0.900).
A new diffusion model (EqDiff-CT) synthesized head and neck CT from CBCT with substantial gains in structural fidelity and Hounsfield unit accuracy compared to CycleGAN and DDPM, potentially improving CBCT-guided treatment planning.
LLM summaries of clinical history for radiology were more comprehensive (37.14% top rating vs clinician, P<.001) and factual (68.05%, P<.001). The proprietary LLM was ranked most useful for protocoling (40.87% rank 1) and interpretation (44.61% rank 1).
Generative AI can serve as a draft assistant for chest radiograph reporting, accelerating workflow and promoting consistency, but requires human-in-the-loop review to mitigate hallucinations.
A DBT foundation model (DBT-DINO) improved breast density classification accuracy (79% vs 73%, p<.001) but did not significantly outperform ImageNet pretraining for 5-year breast cancer risk prediction (AUC 0.78 vs 0.76) or lesion detection (sensitivity 62% vs 67%).
A Vascular Perspective on Osteoarthritis Progression.
In advanced HCC after atezolizumab-bevacizumab failure, HAIC prolonged PFS vs TKIs (weighted median 7.1 vs 3.4 months, P<.001) and had higher response rate (35% vs 5%), with similar overall survival.
