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…
Innovative Responses to Escalating RVU Pressures in Radiology.
Portable low-field MRI is emerging as a clinically relevant adjunct for acute stroke when conventional imaging is unavailable or delayed, supporting stroke-type classification, tissue-based triage in wake-up stroke, and serial post-intervention assessment.
Beyond detection: Does AI see prognosis in mammography?
A review maps AI applications in pediatric neuroimaging across quality/safety, fetal, neonatal, hydrocephalus, malformations, tumors, epilepsy, demyelination, stroke, and trauma, while noting that very few FDA-cleared AI tools are pediatric-specific and highlighting the need for…
In 5,977 patients with LVEF <50%, each ischemic segment on stress perfusion CMR independently raised long-term mortality (HR 1.11 per segment, 95% CI 1.06–1.15). Adding ischemia and LGE to clinical factors and LVEF improved risk prediction (NRI 0.217, p<0.001) over 9 years media…
In 752 brain MRIs, an AI tool analyzing DWI, T2-FLAIR, and SWI sequences for infarcts, hemorrhage, and mass lesions had 92% sensitivity for infarcts (95% CI 86–96), 75% for hemorrhage, and 71% for mass. Agreement with neuroradiologists on protocol adaptation was moderate (κ=0.47…
In a 5-year review of BI-RADS 4C and 5 lesions, radiologist-determined radiology-pathology (rad-path) discordance carried a 47.3% upgrade to malignancy versus 9.4% for concordant benign biopsies, supporting its role in guiding surgical excision.
Demonstrating the real-world impact of an artificial intelligence tool in radiology: are we focusing our efforts in the proper direction?
French guidelines for NMOSD: MRI reveals extensive optic nerve (posterior) and central cord lesions. Diagnose with serum anti-AQP4 antibodies. Treat acute attacks urgently with IV corticosteroids/plasma exchange—don't wait for antibody results.
Patient-Friendly Summary of the ACR Appropriateness Criteria®: Staging and Follow-up of Gastric Cancer.
Patient-Friendly Summary of the ACR Appropriateness Criteria®: Postpartum Hemorrhage.
Patient-Friendly Summary of the ACR Appropriateness Criteria®: Scoliosis-Child.
Adding instructor-led hand-drawn diagrams to conventional instruction significantly improved theoretical knowledge (88.20 vs 82.95) and clinical reasoning (90.50 vs 82.75) for congenital heart disease ultrasound in a 40-resident RCT. Practical skills scores were similar.
Building a Foundation for Radiopharmaceutical Therapy Education.
GRASP DCE-MRI detected significant post-radiosurgery reductions in wash-in slope, wash-out slope, and peak enhancement (p≤.02) in head & neck paragangliomas, suggesting it may serve as a treatment response biomarker.
Rapid MLS automated midline shift quantification on noncontrast CT matched expert neuroradiologists (mean absolute error 0.8 vs 0.9 mm, p<0.0001) in a multicenter study of 153 patients with intracranial pathology. The tool slightly underestimated shifts >10 mm.
Deep learning reconstruction for 3T EDGE-MP2RAGE reduced scan time by 47.7%, increased contrast-to-noise ratio by 85.9% (P<.001) and decreased noise by 22.6% (P=.005) vs standard 3T, with image quality comparable to 7T but better contrast uniformity.
In a retrospective cohort of lecanemab-treated patients, the baseline ALPS-index on DTI predicted the rate of amyloid clearance on PET (β=-6.53, R²=0.20). After adjusting for baseline amyloid burden, both higher ALPS-index and higher baseline burden independently predicted faste…
In 181 healthy older adults, 5-year decline in dopamine D2-like receptor availability on [11C]raclopride PET showed only weak correlations with cognitive decline, and no link to education or leisure activities.
Integrating uncertainty quantification (UQ) into generative models was frequently associated with improved performance or more informative reliability assessment in medical imaging. A systematic review of 41 studies found radiology dominated (29 studies) and 56% of studies were…
Most FDA-cleared AI tools for radiology are in neuroradiology, but very few for pediatrics. Children’s limited exam tolerance, small datasets, and normal age-related variability are cited as barriers.
FDA clears CardIQ Suite (GE Medical Systems) for cardiac CT analysis via 510(k). The radiology committee reviewed under product code JAK.
AI tools improve diagnostic accuracy & efficiency in radiology, but adoption stalls without reimbursement, clinician oversight, and EHR integration. Barriers: implementation costs, bias, limited generalizability. Enablers: clinician-in-loop review, auditable outputs, payment ali…
In a phantom study, models for lung nodule malignancy assessment using only stable radiomic features achieved an AUC of 0.995 versus 0.945 with unstable features, and similarly outperformed for growth prediction (AUC 0.799 vs 0.610). Inter-scanner and tube current variability mo…
