10-minute breast MRI scan beats DBT for invasive cancer
February 25, 2020 -- Breast MRI with an abbreviated scanning protocol -- as short as 10 minutes -- finds more invasive cancers in women with dense tissue than digital breast tomosynthesis (DBT), according to a study published online February 25 in JAMA.  Discuss
MRI pinpoints shoulder stiffness from rotator cuff tears
February 25, 2020 -- Targeting joint capsule abnormalities in the shoulder on MRI scans can help determine which patients with rotator cuff tears will have preoperative shoulder stiffness, according to a study published February 19 in the American Journal of Roentgenology.  Discuss
MRI reveals brain changes from Parkinson's disease
February 24, 2020 -- An MRI technique known as quantitative susceptibility mapping reveals that patients with Parkinson's disease have increased iron deposition in the areas of the brain that handle cognition, memory, and motor function, according to a study published February 20 in the Journal of Neurology, Neurosurgery, and Psychiatry.  Discuss
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
