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
3D printing may improve safety of upper GI surgery
November 7, 2019 -- 3D-printed models of the upper gastrointestinal (GI) tract provided several benefits to the surgical management of a patient with a compressed esophagus -- including improving preoperative planning and intraoperative navigation -- according to a case report recently published online in BMC Surgery.  Discuss
4 core applications of cardiovascular 3D printing
October 28, 2019 -- How are clinicians integrating 3D printing technology into adult cardiovascular medicine? Researchers from the U.S., Switzerland, and China detail a wide range of examples in four core areas in a review article published online October 21 in Interactive Cardiovascular and Thoracic Surgery.  Discuss
Black-blood CT sheds light on intraluminal heart anatomy
October 9, 2019 -- An advanced imaging technique called black-blood CT can leverage cinematic rendering technology to provide a detailed view inside the lumen of vasculature and potentially bolster cardiac evaluation, according to an article published online October 1 in the Journal of Cardiovascular Computed Tomography.  Discuss
New technique unravels 3D MRI scans of placenta
October 3, 2019 -- When applied to 3D MRI, a new mapping algorithm can generate virtual placenta models that open up and flatten -- enhancing the visibility of the placenta during pregnancy, according to an upcoming presentation at the International Conference on Medical Image Computing and Computer Assisted Intervention in China.  Discuss
