MRI scans of 'brain age' could predict poor health
April 25, 2017 -- Researchers combined MRI scans with machine-learning algorithms to develop a "brain age" score that could provide insights into which patients are at risk for poor health and may die at an early age, according to a study published online April 25 in Molecular Psychiatry.
5-minute shoulder MRI could ease patient anxiety
April 19, 2017 -- By taking advantage of parallel imaging on the latest generation of 1.5- and 3-tesla scanners, researchers have devised a quick five-minute shoulder MRI protocol that still produces diagnostic-quality images, according to a study in the April issue of the American Journal of Roentgenology.
Breast MRI: Not just for high-risk women
April 18, 2017 -- Screening breast MRI is a valuable tool in routine clinical practice across a spectrum of women at elevated risk for breast cancer -- not just those who meet the conventional definitions of high risk, according to a study published in the April issue of Academic Radiology.
New study reveals why many MRI scans are delayed
April 14, 2017 -- If MRI scans are running behind schedule on a given day, chances are good that patient-related issues are to blame. More specifically, patient motion, claustrophobia, and late arrivals are the most common reasons, according to a March 26 article in the Journal of the American College of Radiology.
Can machine learning and MRI diagnose depression?
April 13, 2017 -- Can machine learning be used to diagnose serious cases of depression based on data from MRI scans in adults, potentially even before they begin showing symptoms? Yes, it can, according to a proof-of-concept study being published in the June issue of Psychiatry Research: Neuroimaging.
Machine learning could reduce inappropriate knee MRI scans
April 3, 2017 -- Supported by machine-learning technology, researchers have developed a natural language processing algorithm that successfully automates classification of MRI knee scans to better understand MRI utilization, according to a study in the April issue of the American Journal of Roentgenology.
AIUM: Is MRI really needed after MSK ultrasound?
March 29, 2017 -- ORLANDO, FL - MRI exams performed after an initial musculoskeletal (MSK) ultrasound study are nearly always concordant with ultrasound results and rarely change clinical management, according to a Tuesday presentation at the American Institute of Ultrasound in Medicine (AIUM) conference.
fMRI scans may help choose depression treatment strategy
March 27, 2017 -- Researchers using functional MRI (fMRI) have found specific patterns of brain activity that may help determine whether behavioral therapy or antidepressant medication is better for patients with depression, according to research published online March 24 in the American Journal of Psychiatry.
Pediatric radiology abandons linear gadolinium contrast
March 21, 2017 -- Concerns over possible gadolinium retention in the brain have prompted more than half of surveyed pediatric radiology departments in the U.S. to switch from a linear gadolinium-based contrast agent (GBCA) to a macrocyclic GBCA within the past year, according to a study published online March 10 in Pediatric Radiology.
Mobile App Spotlight: A k-Space Odyssey
March 21, 2017 -- AuntMinnie.com presents the next article in an ongoing series highlighting notable mobile apps in radiology. In this installment, we take a look at A k-Space Odyssey, an iOS app designed to facilitate understanding of k-space, the mathematical abstraction that connects MRI scan parameters with the clinical image.
