MRI links lifestyle factors to stroke, dementia risk

August 21, 2018 -- Using MRI, researchers found that lifestyle factors can increase the risk of stroke and dementia later in life among young adults with no clinical evidence of cerebrovascular disease and a seemingly healthy cardiovascular risk profile. The study was published in the August 21 issue of the Journal of the American Medical Association. 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

AI, new cardiac imaging technology can assess for CAD

August 20, 2018 -- The combination of artificial intelligence (AI) and a new noninvasive cardiac imaging technique can perform comparably to current imaging tests used to detect coronary artery disease (CAD) -- without requiring cardiac stress, contrast agents, or radiation exposure, according to research published recently in PLOS One. Discuss

Veterans get inappropriate prostate imaging outside VA

August 17, 2018 -- Veterans who seek care for low-risk prostate cancer receive more imaging that doesn't comply with established guidelines when they go outside of the Veterans Affairs (VA) system to Medicare sources, according to a study published online August 17 in JAMA Network Open. Discuss

6 Steps to Radiology: Part 2 -- The preapplication process

August 17, 2018 -- A new season has started for the Electronic Residency Application Service, and it's never too early to begin getting your ducks in a row. In our second 6 Steps to Radiology article, Dr. James Ireland, Dr. Kedar Jambhekar, and Linda Deloney, EdD, from the University of Arkansas for Medical Sciences offer some guidance. Discuss

MRI helps find contact lens embedded in eye for 28 years

August 17, 2018 -- With the help of MRI, ophthalmologists in the U.K. were able to discover what was causing eyelid swelling in a 42-year-old woman: a hard contact lens that had been embedded in her eye for 28 years. The bizarre case was published on August 10 in BMJ Case Reports. Discuss

Lung cancer overdiagnosis varies widely on CT screening

August 17, 2018 -- The concept of overdiagnosis has bedeviled the mammography screening debate, and it's beginning to show up in CT lung cancer screening as well. A study published online August 13 in JAMA Internal Medicine found an overdiagnosis rate of 67% in a Danish lung screening program -- much higher than rates in other programs. Discuss

5 risk factors help predict brain hemorrhage on CT

August 17, 2018 -- U.K. researchers have identified five factors -- including contrast leakage on CT scans -- that may indicate a higher risk of continued bleeding in the brain of stroke patients. Checking for these factors may help improve survival, according to an article published online on August 14 in Lancet Neurology. Discuss
