Virtual reality engages patients more than CT, booklets
April 25, 2019 -- Patients with an abdominal aortic aneurysm were more engaged and had a better understanding of their condition after examining 3D models using virtual reality technology, compared with CT scans or other educational resources, according to an article published online April 19 in the Annals of Vascular Surgery.  Discuss
3D-printed craniofacial models support family consults
April 22, 2019 -- Researchers from Saudi Arabia have created 3D-printed models based on the CT scans of children with craniofacial deformities. Examining the models significantly increased the parents' likelihood of consenting to surgical treatment, according to a study recently published online in the Journal of Craniofacial Surgery.  Discuss
4 practical applications of VR, AR in radiology
April 19, 2019 -- Virtual reality (VR) and augmented reality (AR) are emerging as key tools for advancing education, communication, and clinical care in radiology. Researchers offer details on several practical applications of the technologies as they are being used throughout various hospitals in an article published online April 16 in Radiology.  Discuss
3D-bioprinted model mimics real human heart properties
April 16, 2019 -- Researchers from Israel have created a 3D-printed model that captures the immunological, biochemical, cellular, and anatomical properties of a real human heart, according to an article published online April 15 in Advanced Science.  Discuss
3 ways cinematic rendering helps visualize the spleen
April 8, 2019 -- Cinematic rendering allowed radiologists from Johns Hopkins University to uncover key features of spleen anatomy and pathology not evident on conventional CT scans -- carving out yet another niche role for the technique, which they detailed in an article recently published online in Diagnostic and Interventional Imaging.  Discuss
Cinematic rendering makes strides in cancer evaluation
April 1, 2019 -- Cinematic rendering proved to be as accurate as conventional volume rendering and CT angiography for presurgical identification of the potential invasion of soft-tissue tumors into major blood vessels, according to an article published online March 27 in the Journal of Computer Assisted Tomography.  Discuss
SIR: Virtual reality beats fluoroscopy for catheter placement
March 26, 2019 -- Virtual reality may be a safer, more time-efficient alternative to conventional fluoroscopy for guiding catheterization, with the potential to increase access to the procedure in rural regions, according to a March 26 presentation at the Society of Interventional Radiology (SIR) 2019 meeting in Austin, TX.  Discuss
MRI-guided cryoablation a boon for HCC patients
March 21, 2019 -- With a 1-tesla open scanner and some finesse, Chinese researchers are using MRI to guide percutaneous cryoablation of hepatic dome hepatocellular carcinomas (HCCs) to almost eliminate tumor progression and extend survival, according to a study published online March 12 in the American Journal of Roentgenology.  Discuss
3D DEXA enhances hip fracture risk prediction
March 11, 2019 -- Combining math-based models with 3D dual-energy x-ray absorptiometry (DEXA) models of the femur enabled clinicians to predict an individual's risk of hip fracture with an accuracy greater than that of standard DEXA and comparable to CT, according to an article published in the April issue of Bone.  Discuss
Augmented reality cultivates early radiology education
March 11, 2019 -- An interactive educational course that uses augmented reality technology to display MRI and CT scans on the user's body improved medical students' image-based understanding of anatomy more than traditional teaching methods did, according to recent research published in Anatomical Sciences Education.  Discuss
