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…

Signify Research, a market intelligence firm that tracks global medical imaging markets, placed 9th in BusinessCloud’s HealthTech 50 for 2026, a UK-wide ranking of innovative healthtech companies.
A bipartisan bill introduced in Congress would authorize $5 million annually over five years to expand access to 4D functional lung imaging software at the VA, aiming to improve diagnosis of respiratory diseases in veterans exposed to burn pits and other hazards.
Florida jury awards $2M after radiologist's misinterpretation of a 20-week fetal ultrasound missed a severe facial cleft, contributing to stillbirth. The parents argued that early detection would have transferred care from a midwife to an OB, preventing preeclampsia complication…
A multiscale fusion model (GAVR) achieved AUC 0.987 in prospective validation for differentiating T4a from T4b gastric cancer on CT. It boosted radiologists' accuracy from 0.609 to 0.795 and cut reading time 60% in a reader study.
Generative AI and Large Language Models in Medical Imaging and Radiation Oncology: Opportunity With Responsibility.
A permuted 2D convolutional neural network suppresses diffuse reverberation noise in ultrasound channel signals to improve image quality. In 15-volunteer liver/kidney scans, the real-time model increased contrast and generalized contrast-to-noise ratio (GCNR), running at 15 fps…
Clinical validation by radiologists is critical for AI in imaging to ensure reliable performance across varying equipment, institutions, and patient demographics. Smooth integration into practice is also essential.
A review maps the progression of AI in MSK radiology from early computer-aided diagnosis to current deep learning and explores emerging large language models and agentic AI for future clinical workflows.
Gd-EOB-DTPA MRI model (non-thin rim enhancement, enhancing capsule, opposed-phase signal loss) plus serum biomarkers differentiated scirrhous HCC from mass-forming cholangiocarcinoma in HBV patients with AUC 0.951 (sensitivity 85.9%, specificity 88.4%), externally validated AUC…
Automatic nnU-Net segmentation of glioblastoma PET/MR achieved Dice scores of 0.76 (MR-enhancing), 0.69 (edema), 0.71 (FET-PET uptake). MR and FET-PET recurrence delineations differed significantly (DSC 0.45, p=0.0497). MR radiomic features could not spatially identify PET findi…
A YOLOv7 deep learning model detected periapical lesions on pediatric panoramic radiographs with sensitivity 76.1% vs 55.2% for dental students, specificity 99.8% vs 97.3%, in a small internal validation study.
In an exploratory multicenter study, a logistic regression model using clinical and CT features predicted CK7 expression in ccRCC with validation AUC 0.714 (95% CI 0.589–0.828).
A multi-task deep learning model using CT images predicted EGFR mutation status in non-small cell lung cancer. Its score was associated with survival in EGFR-treated patients and tumor microenvironment. No performance metrics were reported in the abstract.
In a mouse model of abdominal aortic aneurysm, cyclodextrin-treated mice showed significantly smaller aortic areas (2.31 vs 2.96 mm², p=0.018) and lower elastin-specific MRI enhancement (1.56 vs 2.15, p=0.038), indicating preserved aortic wall integrity, while macrophage imaging…
TEMPO-HCC, a multimodal deep model using MRI and histology, predicted time-specific survival after HCC resection (C-index 0.751, 1-yr AUC 0.836), outperforming staging systems.
