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…

Teledyne will acquire Varex Imaging for $1.1B, adding X-ray tubes and photon-counting detectors to its medical imaging portfolio. The deal, expected to close early 2027, may accelerate next-gen imaging technology for radiologists.
From Dyspnea to Suspected Breast Cancer: A Post-traumatic Hematoma as a Diagnostic Pitfall
<![CDATA[Breast MRI Study Reveals 29 Percent Reduction in Scan Time with Deep Learning Reconstruction and Multi-Shot DWI]]>
RadNet reported a 21.2% aggregate jump in advanced imaging volumes (MRI, CT, PET/CT) in Q2 compared to last year, leading the company to raise its 2026 revenue forecast to over $2.42 billion. Same-center advanced imaging volumes grew 9.6%, outpacing routine exams.

Pediatric radiologist Fariba Goodarzian, MD, appointed radiologist-in-chief at Children’s Hospital Los Angeles, where she has worked >25 years; will oversee MRI, CT, nuclear medicine, and interventional radiology.
In a phantom study, a 30-40% data extraction percentage for data-driven gating combined with deep learning PET reconstruction (AiCE-i) yielded optimal balance between image noise and respiratory motion effects.
Gemini 3.0 achieved mean Dice 0.935 for zero-shot STS segmentation (radiologist inter-rater Dice 0.949). Tumor size from masks had ICC 0.976 vs 0.922 for direct LLM estimate (p=0.027), with bias -0.5 mm vs -5.0 mm. Segmentation-derived measurements are more reliable.
Imaging evaluation of liver metastases is evolving from purely morphologic assessment to biologically informed techniques. Advanced imaging, radiomics, and artificial intelligence can assess tumor biological heterogeneity, guide therapy, and predict outcomes.
Pairing hip X-ray or MRI with radiology text descriptions boosted multimodal LLMs' detection of femoral head osteonecrosis: AUC 0.91 vs 0.55 for image-only, and staging reliability ICC 0.97 vs 0.51. Multi-image input offered no benefit.
Applying conformal prediction to vision-language model report drafting for chest X-rays, high-confidence outputs showed significantly better agreement with radiologist impressions (P<0.001) and higher classification AUROC (P<0.05).
CT radiomics-based SVM model predicted early treatment response in advanced NSCLC, with AUC 0.90 (95% CI 0.82-0.97) for chemo-immunotherapy and 0.84 (95% CI 0.73-0.95) for immunotherapy, externally validated.
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.
French radiology is advancing with innovations in dual-energy and photon-counting CT, AI for cancer diagnosis, and interventional radiology, enhancing diagnostic accuracy and patient outcomes.

Multidisciplinary guideline recommends pre- and post-reduction imaging, biomechanical reduction first, 1-week immobilization, and surgery for age <40, contact sports, or bone loss (low GRADE evidence).
Letter to the Editor: Concordance of vibration-controlled transient elastography and magnetic resonance elastography for fibrosis staging in patients with metabolic dysfunction-associated steatotic liver disease.
Letter to the Editor: Autonomous robotic thrombectomy should be considered a near-term frontier for AI-enabled interventional radiology.
Current AI scribe assessments focus on initial note drafts, but signed clinical notes are dynamic—errors can compound as content is copied, coded, and re-ingested by downstream tools. Safety must be measured by tracking these cascading effects across the patient record.

Heparin Resistance During Iliocaval Thrombectomy in a Hypercoagulable Patient.
For knee OA, weight loss, exercise, and education remain core interventions for preserving joint healthspan. Genicular artery embolization may help in synovitis-dominant cases but lacks consistent sham-controlled evidence.
In a pilot study of 30 children with neuroblastoma, T2-weighted MRI radiomics with XGBoost achieved an AUC of 0.88 for distinguishing high-risk from low/intermediate-risk tumors, suggesting potential as a noninvasive imaging biomarker.
A deep learning model using longitudinal CT radiomics predicted rib fracture risk after stereotactic body radiotherapy in NSCLC patients, achieving an AUC of 0.792 on validation. The model-predicted high-risk group had a hazard ratio of 10.82 compared to the low-risk group.
