Venous stent placement in the legs is safe and effective
Using venous stents for thrombotic and nonthrombotic venous occlusive disease in the legs is safe and effective, improving vein disease severity scores, increasing the diameters of treated veins, and delivering long-term patency rates, according to researchers at the Stanford University School of Medicine.


MRgFUS is effective for bone metastasis and osteoarthritis pain
Magnetic resonance-guided focused ultrasound may be a promising treatment for chronic pain from musculoskeletal diseases and bone metastases. A multi-institutional Japanese study showed reduced pain at the site of most severe tenderness in patients with bone metastases, lumbar facet joint osteoarthritis, and knee osteoarthritis.

MRI plus 18F-FDG PET/CT recommended, with caveats, to identify gliomas
Combining MRI with FDG PET/CT more effectively diagnoses and/or defines glioma grade than does MRI alone, according to an Australian study. However, the researchers caution that due to limited sensitivity and negative predictive values, negative scans should not guide decisions where surgery would be recommended.


Diagnostic AI system validated for breast MRI
Machine learning systems capable of differentiating malignant from benign breast lesions on dynamic contrast-enhanced MRI are expected to reduce variability in diagnostic classification and increase interpretation speed. Researchers described training and testing a system in 2,000 Chinese women with lesions and masses on breast MRI.


Musculoskeletal ultrasound aids diagnosis and treatment of rheumatoid arthritis
MSK-ultrasound of the hands and feet helps physicians diagnose and guide treatment decisions in RA, according to a study in the November 2019 European Radiology. Ultrasound outperformed conventional assessment of disease activity in patients with inflammatory joint pain and modified treatment for half patients in the study.

Torso CT in blunt trauma patients with normal vital signs can be avoided
Contrast-enhanced computed tomography of the torso in high-energy blunt trauma patients rapidly detects injuries, identifies the need for interventional radiology, and can reduce unnecessary surgery. But Italian radiologists and trauma physicians recommend that it not be routinely performed in patients who are hemodynamically stable with normal laboratory results and diagnostic imaging.
