Virtual reality shows value in x-ray patient positioning
January 13, 2020 -- Virtual reality technology enables student radiographers in Australia to simulate the entire process of acquiring an accurate x-ray exam with greater efficiency and ease than with the standard training method of clinical role-play, according to a study published in the February issue of Radiography.  Discuss
4D CT sheds light on post-TAVR treatment strategies
January 8, 2020 -- 4D CT scans showed that an anticoagulant-based treatment strategy was more effective than antiplatelet medication at reducing the risk of valve leaflet abnormalities after transcatheter aortic valve replacement (TAVR) in a recent study, published in the January 9 issue of the New England Journal of Medicine.  Discuss
Cinematic rendering enhances view of vascular anomalies
January 2, 2020 -- Radiologists from Johns Hopkins University applied cinematic rendering to the clinical management of congenital vascular anomalies and uncovered critical features of patient anatomy and pathology that were not evident using traditional volume rendering techniques or conventional CT.  Discuss
3 ways to advance 3D printing in radiology
December 19, 2019 -- How can leaders in radiology prepare for the growing integration of 3D printing in clinical practice, and what measures can they take to help ensure its success?

Focused ultrasound treatment to brain relieves tremors
November 26, 2019 -- Applying treatments of MR-guided focused ultrasound to the brain can be an effective therapy for people with essential tremor, as well as tremor related to Parkinson's disease, according to a study to be presented at RSNA 2019 in Chicago.  Discuss
Is this MRI-guided procedure worthy of epilepsy patients?
November 25, 2019 -- An MRI-guided therapy for patients with epilepsy who are resistant to drug treatment has shown that it can extend quality of life. But the technique also comes at a greater cost than surgery, according to a study published online November 20 in PLOS One.  Discuss
MEG helmet enables 3D functional brain imaging in kids
November 18, 2019 -- Researchers from the U.K. have retooled their prototype magnetoencephalography (MEG) scanner to be able to capture 3D brain images of active adults and children. The new device may improve current understanding of brain development and neurological conditions, according to an article recently published online in Nature Communications.  Discuss
New method estimates postsurgical AAA rupture risk on CTA
November 15, 2019 -- A new biomechanics technique can estimate the long-term prognosis of abdominal aortic aneurysms (AAA) after surgical repair by analyzing CT angiography (CTA) scans, according to an article recently published online in Frontiers in Bioengineering and Biotechnology.  Discuss
3D printing helps unravel rare cardiac anomalies
November 14, 2019 -- A 3D-printed heart model based on patient MR images helped physicians identify two uncommon cardiac anomalies in a case report published online November 11 in Clinical Imaging. The technique may be a viable alternative to more invasive procedures, such as cardiac catheterization, researchers say.  Discuss
