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…
Combining intratumoral plus 3-mm peritumoral CT radiomics features with clinical variables achieved AUC 0.891 for predicting MSI status in gastric adenocarcinoma, outperforming clinical-only model (AUC 0.771) in a dual-center study.
Chest X-ray biological age predicts 30-day mortality after TAVI (AUC 0.952 vs 0.745 for EuroSCORE II) and surgical procedures, with 10-year excess biological age linked to higher complications (17.3% vs 9.2%).

Lateral geniculate nucleus (LGN) volume on 7T MRI is similar in moderate vs advanced retinitis pigmentosa (p=0.91), but right LGN consistently larger than left (p<0.001).

In a multicenter study of 1306 children, age-adjusted MPA/AA ratio on chest CT predicted invasive pulmonary arterial pressure elevation with an AUC of 0.881 (95% CI 0.830-0.932). The ratio declines with growth, so age-specific norms are needed.
Infiltrative pancreatic acinar cell carcinoma (Type 3) and larger tumor size independently predicted recurrence after curative resection (HR 7.7, 95% CI 1.1-53.6; HR 1.7 per cm, 95% CI 1.2-2.3). Three CT/MRI subtypes identified.
A 3-point CT score (upper-lobe irregular lines, pleural surface irregularity, basal reticulation) detected histopathological usual interstitial pneumonia (UIP) features with AUCs of 0.83 and 0.89 in two cohorts, and independently predicted disease progression at 1 and 2 years.
In a 120-month study of 134 patients with unifocal T1aN0M0 papillary thyroid carcinoma, disease progression-free survival was not statistically different between microwave ablation (MWA) and surgical resection. MWA had numerically fewer complications and no permanent ones.
A combined radiomic-clinical model predicted invasiveness of pure ground-glass nodules (pGGNs) with an AUC of 0.832 in the test set, outperforming a clinical model (AUC 0.733). SHAP analysis identified the most important radiomic feature.
SVM-RBF model integrating clinical, pain, and imaging data predicted drug-refractory trigeminal neuralgia with test AUC 0.824 and validation AUC 0.806; Cox models showed moderate short-to-medium discrimination but limited long-term accuracy.
An AI model for detecting pneumoperitoneum on abdominal CT achieved 84.3% sensitivity and 89.6% specificity in an external validation set. Sensitivity increased to 96% when cases with <1 mL free gas were excluded, showing strong performance for clinically relevant volumes.
WFUMB: Ultrasound fusion with CT/MRI improves visibility of occult liver lesions, enabling ablation in up to 95% of cases. Target registration errors ~4-14 mm in clinical use, with major complications <2%.
In healthy adults and autoimmune limbic encephalitis patients, the HIPS-THOMAS method surpassed standard FreeSurfer segmentation for delineating thalamic nuclei. Standard FreeSurfer also underperformed in distinguishing patients from controls based on affected anteroventral and…
PRGen, a disease-guided generative model trained on 50,127 text-image pairs, synthesizes controllable panoramic radiographs. Adding generated images to training boosted segmentation Dice 47.59% and AUC 11.53%; >82% of images deemed clinically realistic. External validation showe…

In 115 patients undergoing cone-beam CT-guided percutaneous pelvic screw fixation, S1/S2 intra-sacral corridor height varied substantially (median 23 mm, range 10–32 mm). However, no significant correlation was found between corridor height and operative time (ρ=0.043) or radiat…
AI-assisted CXR interpretation significantly improved traumatic pneumothorax detection for emergency physicians (diagnostic accuracy OR 2.37, p<0.001). Non-specialists benefitted more than specialists, with a significant AI-by-experience interaction (p=0.010). Specificity was un…
A dynamic curriculum learning framework for spatiotemporal encoding outperformed existing methods on six brain imaging tasks including Alzheimer's and tumor classification.
Radiology was a high-density domain in 368 AI-in-healthcare systematic reviews; 68% of data from imaging, electronic health records, labs; ethical concerns in 78.5% (rising 2021–2025).
Fully automated AI-based coronary artery calcification quantification on low-dose CT for lung cancer screening showed excellent agreement with semi-automated scoring (ICC 0.96) and high sensitivity (0.97) for excluding CAC, without extra reading time.
