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…

Caution Needed When Applying Vision-Language Models for Chest Radiography Nodule Screening.
The Role of Visual Language Models in the Management of the Axilla in Breast Cancer.
Important Reminders When Using Propensity-Score Matching.
Small and pure ground-glass lung nodules are the ones most often missed on chest computed tomography (CT), especially near vessels or airways. Reader fatigue and bias also contribute. Knowing these patterns helps radiologists use technical and cognitive strategies to reduce miss…

Radiology Economics Forecast: Is It Doom and Gloom?
In 175 patients, a preoperative MRI connectome model predicted long-term seizure recurrence after temporal lobe epilepsy surgery with 80.0% specificity and 63.9% negative predictive value, outperforming clinical variables.
An ECG-only deep-learning model predicted respiratory-induced liver motion with a mean absolute error of 2.83 mm during normal breathing and 4.02 mm overall, with correlation coefficients above 0.90 in eight volunteers.
AI volumetric segmentation after vestibular schwannoma radiosurgery tracked internal regrowth with median Dice 0.85 vs expert reads; internal regrowth was just 4.7% of cases but accounted for 27% of radiographic failures (170 MRI scans, 85 patients).
FAPI PET/CT showed 93.0% sensitivity vs 76.5% for FDG (p=0.002) in 176 patients with suspected HPB cancers. Nodal accuracy was 86.8% vs 71.1%. Dual-tracer approach did not improve accuracy. Prospective validation needed.
In chronic subdural hematoma, a contralateral middle meningeal artery (MMA) larger than the ipsilateral by ≥0.2 mm predicted additional collaterals: 93.75% vs 35.78% (p<0.001). Ipsilateral MMA ≤1.384 mm also predicted collaterals (p<0.001).
Similar 90-day functional outcomes for tenecteplase vs alteplase before thrombectomy in patients ≥80 with large-vessel occlusion stroke (mRS ≤3: 48.0% vs 43.5%; OR 1.20, 95% CI 0.86–1.67).
In a 77-patient cohort with knee osteoarthritis, adding Lipiodol to imipenem/cilastatin genicular artery embolization did not improve long-term outcomes; early pain reduction at 1 month was greater (p=0.024). Both regimens were safe.
Only one-third of patients received osteoporosis medication after vertebral augmentation. The incidence of new vertebral fractures fell from 0.519 to 0.076 per person-year after starting medical management (incidence rate ratio 6.79, 95% CI 3.37-15.51), a 6-fold decreased risk.
Survival According to Radiomic and Visual UIP Classification in Fibrotic ILD.
Low-molecular-weight heparin (LMWH) remains first-line for venous thromboembolism in pregnancy and breastfeeding; vitamin K antagonists are contraindicated at 6–12 weeks and third trimester, and direct oral anticoagulants are contraindicated throughout.

Survey of 215 breast radiologists: only a minority see meaningful clinical benefit. Actual callback rate dropped ~35%, but unnecessary biopsies only ~9%, and just 29.4% of AI users reported notable burnout reduction.
RadNet Experiences Significant Growth in Advanced Imaging Procedures
A consortium of 12 U.S. hospital systems aims to build AI workflows for radiology to speed interpretation and improve outcomes, with data sharing across ~20M patients/yr. First results 2027.

In a single-center survey of 10 IR attendings, a night-float call system increased sleep (6 vs 5.5 hrs), was preferred by 60%, and reduced wRVUs per FTE by 6% compared to traditional 24-hour call.
Solis Mammography opened 4 new centers in Colorado, North Carolina, and Florida, offering 3D mammography and AI services including Mammo+Heart for breast arterial calcification. The company now operates over 170 locations.
The best diagnosis is in this patient with cough and fever.
A narrative review finds that global radiology remains dominated by short-term outreach models, neglecting the systems issues—workforce, equipment maintenance, financing, and governance—required for sustainable, equitable imaging services.
