Virtual reality supports patient care, medical education
August 24, 2018 -- Virtual reality technology may have a wide range of medical applications that extend beyond gaming and entertainment, say researchers from Pennsylvania. Their proprietary virtual reality program, for example, has helped reduce stress and anxiety for cancer patients awaiting radiation therapy.  Discuss
Cinematic rendering bolsters AI for depth estimation on endoscopy
August 21, 2018 -- The photorealistic quality of cinematically rendered CT scans may reduce the amount of imaging data needed to train artificial intelligence (AI) algorithms for medical endoscopy applications, according to an August 16 accepted manuscript in Physics in Medicine and Biology.  Discuss
Physicians prefer cinematic rendering for ankle injuries
August 20, 2018 -- Cinematically rendered images based on CT scans of the ankle are more photorealistic and depict relevant findings better than conventional volume-rendered 3D reconstructions, according to an article published online August 14 in the American Journal of Roentgenology.  Discuss
3D-printed hips may improve complex fracture diagnosis
August 8, 2018 -- Radiology residents who examined 3D-printed models of an acetabular fracture based on hip CT scans had a marked improvement in their understanding of the condition, according to an article published online recently in Academic Radiology. This could benefit the accuracy of their diagnostic reports.  Discuss
3D-printed breast phantoms help refine mammography
July 30, 2018 -- Researchers from Maryland have developed new 3D printing software for creating patient-specific 3D-printed breast phantoms that could help enhance the evaluation of mammography devices, according to an article published in the July issue of the Journal of Medical Imaging.  Discuss
VR software may increase MRI segmentation efficiency
July 26, 2018 -- Using new virtual reality (VR) software to correct segmentation errors on MRI scans allowed users to complete the task more quickly and accurately compared with using a conventional 2D interface in a new study, published online July 20 in the Journal of Digital Imaging.  Discuss
New Zealand start-up scans 1st humans with spectral CT
July 18, 2018 -- Researchers from a start-up company in New Zealand have scanned the first humans with a spectral CT scanner based on solid-state digital detectors. The technology produces color images at much higher levels of resolution than traditional CT scanners and, thus, may improve diagnosis.  Discuss
VR, AR may revamp cardiovascular imaging
June 28, 2018 -- Advances in virtual reality (VR) and augmented reality (AR) have prompted new developments in cardiovascular imaging that may improve clinician training as well as patient care and outcomes, according to a review article in the June issue of JACC: Basic to Translational Science.  Discuss
Virtual reality adds depth to brain aneurysm diagnosis
June 20, 2018 -- Radiologists detected brain aneurysms just as accurately by examining CT scans with a virtual reality device as they did by reviewing conventional CT angiography and 3D rotational angiography scans, researchers reported in the July issue of Clinical Neurology and Neurosurgery.  Discuss
New 3D CT technique tops x-ray for diagnosing arthritis
June 19, 2018 -- Researchers from the U.K. have developed an algorithm capable of detecting subtle changes in the spacing between arthritic joints on 3D-reconstructed CT scans better than even standard x-ray imaging can, according to an article published online on June 18 in Scientific Reports.  Discuss
