DTI-MRI charts brain changes in young football players October 24, 2016 -- Diffusion-tensor MRI (DTI-MRI) scans have shown significant brain changes in young football players after just one season of games and practice, even when they appear concussion-free, according to a new study published online October 24 in Radiology.
Abstinence before prostate MRI offers benefits in over 60s October 5, 2016 -- Abstinence from ejaculation prior to a prostate MR examination significantly increases the volume of seminal vesicles (SVs), and thereby may well improve evaluation of SV invasion on multiparametric MRI, especially in older men, according to new research from Turkey and the U.S.
Rat study finds no brain abnormalities from GBCAs October 4, 2016 -- An evaluation of two linear gadolinium-based contrast agents (GBCAs) showed no signs of abnormalities in the brains of rats despite the presence of gadolinium. What's more, researchers found that gadolinium levels had decreased markedly 20 weeks after GBCA injection, according to results published online September 27 in Radiology.
MRI initiative will chart brain development in children September 22, 2016 -- Researchers at the University of North Carolina at Chapel Hill and the University of Minnesota are about to embark on a groundbreaking four-year journey to track and analyze the highly dynamic evolution of a child's brain between birth and age 5 through regularly scheduled MRI scans.
MR/TRUS fusion biopsy targets high-risk prostate cancer September 20, 2016 -- Targeted prostate biopsies guided by fused MR and transrectal ultrasound (TRUS) images can detect more cases of aggressive prostate cancer than traditional systematic biopsies guided by TRUS alone, according to a multicenter study published recently in Urologic Oncology: Seminars and Original Investigations.
Zika's rapid spread on MRI scans shocks researchers September 13, 2016 -- Researchers using MRI to study the Zika virus in a pregnant monkey said they were "shocked" at how quickly the virus spread from the animal to its fetus. The findings could shape efforts to develop a vaccine for the disease, according to a study published online September 12 in Nature Medicine.
Teamwork improves safety for MRI scans of cardiac devices September 9, 2016 -- Radiologists at Emory University are getting by with a little help from their electrophysiology friends. Together they are successfully ensuring the safety of patients with cardiac implantable electronic devices during MRI scans, according to a paper published in the September issue of the American Journal of Roentgenology.
JAAOS: X-ray still best for knee pain screening September 9, 2016 -- Despite the power of MRI, x-ray is still the best tool for screening patients ages 40 years and older who have knee pain, according to a new study in the September issue of the Journal of the American Academy of Orthopaedic Surgeons.
DTI-MRI links key brain regions to cognitive disorders September 7, 2016 -- Using diffusion-tensor MRI (DTI-MRI), researchers have located two areas of the brain with increased atrophy, infarctions, and lesions that collectively create a kind of logjam that contributes to cognitive impairment and/or dementia, according to a paper published online September 6 in Radiology.
MRI scans during 1st trimester of pregnancy are safe September 6, 2016 -- MRI in the first trimester of pregnancy does not put the fetus at increased risk of stillbirth, birth defects, hearing loss, or childhood cancer, according to a study published in the September 6 issue of the Journal of the American Medical Association.
