Could contrast mammo supplant CE-MRI for confirming breast cancer?
February 21, 2020 -- Contrast-enhanced (CE) mammography might be better suited than contrast-enhanced MRI for confirming some cases of suspicious breast cancer -- especially when radiation dose-reducing protocols are used, according to a study published February 14 in the Journal of Magnetic Resonance Imaging.  Discuss
AI predicts heart attack, stroke on cardiac MRI
February 21, 2020 -- An artificial intelligence (AI) algorithm that quantifies blood flow on cardiac MRI can predict -- perhaps better than a physician can -- if a patient will have a heart attack or a stroke, according to research published online February 14 in Circulation.  Discuss
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
