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…
A clinically oriented narrative review proposes an adaptive AI cascading model for Alzheimer’s disease, integrating blood biomarkers and selective imaging escalation to mirror real-world workflows and improve clinical translation.
External validation of knee OA progression DL models drops median AUC from 0.81 to 0.75; surgery prediction models (AUC 0.87) may reflect access to care, not disease, per review of 33 studies.
In a multicenter study, SAGE-derived habitat analysis with RBF-SVM differentiated meningiomas, brain metastases, and gliomas with internal macro-AUC 0.700±0.086. External validation macro-AUC was 0.629. A simpler model using mean features alone gave external macro-AUC 0.849.
Dentin-normalized CBCT radiomics with XGBoost achieved an AUC of 0.78 for differentiating periapical granulomas from radicular cysts, significantly higher than raw radiomics (AUC 0.68, P<.05).

An externally validated random forest model predicted radiographic adjacent segment degeneration after short-segment lumbar fusion (AUROC 0.782 internal test, 0.749 external). Five perioperative variables were integrated; preoperative intervertebral space height was the stronges…
In cancer patients with chronic subdural hematoma, middle meningeal artery embolization (MMAE) was associated with lower 90-day mortality vs medical management (15.3% vs 20.9%; HR 0.69) and fewer rescue surgeries when added to surgery (8.8% vs 13.7%; HR 0.63).
Vertebral level vs. kidney border for predicting postnatal low conus on fetal MRI: no significant accuracy difference (p=0.66). Postnatal confirmation in 65% of 34 imaged fetuses.
Parent artery plaque enhancement (PAPE) and aneurysm wall enhancement (AWE) on preprocedural vessel wall MRI independently predicted new DWI-positive microembolic events after endovascular treatment of unruptured intracranial aneurysms, with quantitative parent artery enhancemen…
A CT radiomics-based model achieved a test-set AUC of 0.745 for predicting EGFR mutation in stage IA non-small cell lung cancer; incorporating clinical variables modestly improved performance.
ChatGPT outperformed 4 other LLMs in providing microwave ablation guidance, achieving the highest mean quality score (3.65/4) when rated by radiologists. Claude and DeepSeek followed (3.47), while Gemini (3.00) and Meta (2.95) scored lower, suggesting potential for clinical deci…
A Fuzzy Residual-ShuffleNet deep learning model achieved 94.999% accuracy, 95.899% sensitivity, and 93.889% specificity for breast cancer detection on mammograms in a retrospective study.
An AI model combining ConvNeXtV2 and YOLOv8 with genetic algorithm tuning achieved 78.4% precision, 53.6% recall, and 62.6% AP50 for detecting dental caries on panoramic radiographs, outperforming baseline YOLOv8.
This educational review details MRI-based oxygen extraction fraction (OEF) mapping techniques. Quantitative BOLD (qBOLD) and quantitative susceptibility mapping (QSM) are foundational, but hybrid QSM-qBOLD methods jointly use magnitude and phase data to improve source separation…

AI can transform radiology education by enabling automated needs assessments, personalized learning pathways, and synthetic board-style question generation, though cost, bias, and privacy concerns must be addressed.
Radiologists can review thoracic manifestations of obstetric and gynecologic disease, from preeclampsia and embolism to metastatic tumors and benign syndromes like Meigs syndrome, to aid timely diagnosis.

CSF shunt failure: 14% at 1 month, 40% at 1 year, 50% at 2 years. Early complications: tip misplacement, improper connection; late: fracture, erosion, overdrainage. Obstruction, infection, or migration possible anytime.
Understanding lateral pelvic anatomy on MRI is crucial for detecting deep endometriosis and guiding surgical planning. A multidisciplinary approach improves preoperative staging and helps avoid misdiagnosis.
Role of Dual-Energy CT in Cholelithiasis and Associated Complications.
Radiologists should recognize local, regional, and distant patterns of lung cancer recurrence on post-treatment chest CT. Disseminated forms include aerogenous, miliary, pleural, and lymphangitic metastases. Early detection of these patterns can improve patient care.
