3D printing lowers risk and cost of testing FFR-CT
November 27, 2017 -- CHICAGO - What if there were a low-risk, cost-effective way to validate the numerous fractional flow reserve CT (FFR-CT) technologies in development? Patient-specific 3D-printed coronary models may be the answer, according to a study presented on Monday at RSNA 2017.  Discuss
Artificial intelligence may help bridge experience gap for liver CEUS
November 9, 2017 -- Can a computer-aided diagnosis system based on machine learning characterize focal liver lesions on contrast-enhanced ultrasound (CEUS) cine clips as accurately as an expert reader? It's certainly possible, if research published online recently in Radiology is any indication.  Discuss
Image analysis with 3D modeling aids wound healing
October 24, 2017 -- Researchers have proposed a novel approach to chronic wound healing that involves image analysis combined with 3D modeling and bioprinting. They have used wound images from patients with diabetes, burns, and metabolic conditions that can cause tissue death.  Discuss
Gaming technology armed to reduce repeat x-rays
October 18, 2017 -- Video game technology is being used for much more than simply playing games these days. Case in point: A motion-sensing device for gaming consoles can now be used to help set x-ray exposure parameters, reducing repeat exams, according to a study published online in Pediatric Radiology.  Discuss
Portable gaming sensor enables 3D scans of elephantiasis
October 18, 2017 -- A portable infrared sensing device can produce rapid and accurate 3D scans of legs affected by elephantiasis, according to a study published online October 16 in the American Journal of Tropical Medicine and Hygiene.  Discuss
How augmented reality can transform medical imaging
October 12, 2017 -- Moving from lightboxes and x-ray film to 3D holographic images of patient anatomy, radiology has experienced incredible technological advances in recent years. And there's more to come: Pediatric radiologist Dr. Jesse Courtier believes the specialty is on the cusp of yet another exponential transformation.  Discuss
How radiologists can optimize their role in 3D printing
October 9, 2017 -- The vision of combining 3D printing and healthcare is now a reality. What can radiologists do to get started, and how can they maximize their role in the field? A panel of 3D printing experts discussed such questions and more in a September 28 webinar.  Discuss
3D-printed model helps prepare for stroke clot removal
October 6, 2017 -- A 3D-printed brain perfusion phantom can be a useful tool for interventional radiologists, neurosurgeons, and neuroradiologists to practice performing mechanical thrombectomy for interventional treatment of stroke, according to a team from the University of Connecticut Health Center in Farmington, CT.  Discuss
Researchers visualize cardiac conduction system in 3D
September 13, 2017 -- A multinational research group has used 3D reconstruction of micro-CT images to visualize -- for the first time in 3D -- the group of cells that cause the heart to beat. The method shows promise for helping cardiologists plan heart surgeries and achieve better patient outcomes.  Discuss
AJR papers shine spotlight on cinematic rendering
August 25, 2017 -- It's been touted as "3D on steroids," but many in radiology still aren't sure how cinematic rendering of medical images works. Fortunately, two papers in the August edition of the American Journal of Roentgenology offer an explanation of the new technique, which creates stunningly lifelike images from scans.  Discuss
