MRI finds cancer missed on clinical breast exams

February 12, 2020 -- Breast MRI scans found six cases of breast cancer in high-risk women that had been missed with clinical breast examinations in a recent study, published in the March issue of Clinical Radiology. But the MRI scans also led to more recalls -- in excess of established guidelines. Discuss

Could a plant virus help create a new MRI contrast agent?

February 10, 2020 -- What's old is new for University of Texas at Dallas (UTD) researchers who are resurrecting an organic, biodegradable compound that someday might be the foundation for a nongadolinium-based MRI contrast agent, according to a preclinical study published online on February 5 in Chemical Science. Discuss

AI may help improve management of stroke patients

February 5, 2020 -- Artificial intelligence (AI) algorithms can determine from multiparametric MRI exams if a stroke patient's symptoms began within 4.5 hours -- the recommended window of time for a patient to be treated with thrombolysis, according to research published online January 28 in Stroke. Discuss

Deep learning distinguishes between Alzheimer's, iNPH

February 3, 2020 -- A deep-learning algorithm can differentiate between Alzheimer's disease and idiopathic normal pressure hydrocephalus (iNPH) on MRI scans at a comparable accuracy to radiologists, according to research published online January 22 in Magnetic Resonance in Medical Sciences. Discuss

MRI scoring system improves ovarian cancer detection

February 3, 2020 -- Researchers from France and the U.K. have developed an MRI-based, five-point scoring system that can distinguish between malignant and benign ovarian cysts with an accuracy of 90% when ultrasound exams are inconclusive, according to a study published January 24 in JAMA Network Open. Discuss

MRI data show smoking, alcohol age the brain

January 31, 2020 -- It is no secret that excessive smoking and alcohol consumption harm one's health. Now, MR images and a machine-learning metric show that these bad habits also can age the brain prematurely, according to a study published online on January 30 in Scientific Reports. Discuss

No signs of residual gadolinium after MR arthrography

January 29, 2020 -- No signs of residual gadolinium uptake in the brain were found following intra-articular administration of a gadolinium-based contrast agent (GBCA) for MR arthrography in a new study, published online January 25 in Skeletal Radiology. The findings indicate that residual gadolinium may not occur with intra-articular use. Discuss

Deep learning could help MS patients avoid GBCA MRI

January 28, 2020 -- With the aid of a deep-learning model, a team of researchers has detected with greater than 70% accuracy active lesions in patients with multiple sclerosis (MS), potentially helping them avoid repeat MRI scans and multiple doses of gadolinium-based contrast agents (GBCAs), according to a study published in the February issue of Radiology. Discuss

Study supports interval MRI for likely benign findings

January 27, 2020 -- Major cancer organizations recommend interval MRI screenings for women with a breast MRI finding likely to be benign. But are these follow-up screenings of patients categorized as BI-RADS 3 effective for catching cancer? New research shows they are -- to a certain extent. Discuss

MRI shows air pollution effect on kids' brain development

January 24, 2020 -- Air pollution is not only bad for the lungs, it could be bad for the brain as well -- especially in children. Brain MR images showed reduced gray-matter volume in kids who were exposed to high levels of traffic-related air pollution since birth, according to a January 24 study in PLOS One. Discuss
