Magnetic Resonance Imaging (MRI) News and Research

RSS

Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord. Also called: Magnetic resonance imaging, NMR, Nuclear magnetic resonance.

YM BioSciences begins enrollment in CYT387 Phase II trial for myelofibrosis

YM BioSciences Inc. today announced that it has enrolled the first patients in its multi-center Phase II trial of CYT387 administered twice-daily (BID) for the treatment of myelofibrosis.

WPI professor receives AHA fellowship for research into cardiovascular disease

Dalin Tang, professor of mathematical sciences and biomedical engineering at Worcester Polytechnic Institute (WPI), has been elected a fellow of the American Heart Association (AHA). Tang was elected to fellowship by the AHA's Council on Basic Cardiovascular Sciences in recognition of his "major and productive contributions in cardiovascular basic science."

Scientists discover mechanism behind MRI-induced vertigo

A team of researchers says it has discovered why so many people undergoing magnetic resonance imaging (MRI), especially in newer high-strength machines, get vertigo, or the dizzy sensation of free-falling, while inside or when coming out of the tunnel-like machine.

MRI screenings for breast cancer benefit high-risk, underserved women

Using breast magnetic resonance imaging (MRI) screenings among targeted, high-risk, underserved women significantly decreased diagnostic cost and increased patient compliance rates with follow-up compared to using general risk mammography screenings.

Enrollment commences in MINI-AMI study of Impella in STEMI patients

Abiomed, Inc., a leading provider of breakthrough heart support technologies, today announced the first patient enrolled in MINI-AMI, an FDA prospective, randomized, controlled multi-center study to assess the role of 24-hours of direct unloading of the left ventricle with Impella 2.5 support to reduce infarct size in patients with ST-elevation myocardial infarction (STEMI) without cardiogenic shock.

ALS damages neurons in parts of the brain responsible for cognition and behaviour

Recently published studies by a researcher in the Faculty of Medicine & Dentistry demonstrate that ALS - known as Lou Gehrig's disease - damages neurons in parts of the brain responsible for cognition and behaviour.

Researchers use MRI and PET/CT to assess safety, efficacy of heart drug dalcetrapib

Researchers from Mount Sinai School of Medicine have for the first time used several imaging techniques to prove the efficacy of a promising new treatment for atherosclerosis—the build-up of plaque in artery walls that can lead to a heart attack.

Women with BRCA gene mutation develop breast cancer earlier than their ancestors

Women with a deleterious gene mutation are diagnosed with breast cancer almost eight years earlier than relatives of the previous generation who also had the disease and/or ovarian cancer, according to new research from The University of Texas MD Anderson Cancer Center.

Cam impingement may increase risk of hip OA in young men

Hip impingement may be a risk factor of osteoarthritis (OA) of the hip. A new study reveals that the presence of an underlying deformity, known as cam impingement, is associated with hip damage in young men without any arthritis symptoms and detected using magnetic resonance imaging.

Stroke in the young on the rise: Study

A new study has revealed that more children and young adults in the U.S. are having strokes. Researchers speculate that unhealthy lifestyles could be a likely contributor.

Magnetic resonance imaging may predict survival in patients with advanced rectal cancer

A new study has shown that magnetic resonance imaging (MRI) used to evaluate responses to pre-surgery (neo-adjuvant) chemotherapy or radiation may predict survival among patients with advanced rectal cancer.

Scientists discover nanoparticles can disrupt intracellular transport pathways

Scientists at the Centre of Cancer Biomedicine at the Norwegian Radium Hospital are the first to show that uptake and accumulation of nanoparticles in cells can disrupt important intracellular transport pathways.

Fluctuations in brain signals explained: Spontaneous electrical background rhythms in the brain influence fMRI

Until now, brain scans obtained using fMRI – one of the most important imaging methods in use today – have been affected by fluctuations in the brain activity measured which could not be explained. Researchers at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig and the Charité in Berlin have now shown that certain electric background rhythms in the brain, known as Alpha oscillations, alter the fMRI signal obtained with visual stimuli. To do this, they used a new approach in which quickly changing brain activity, which cannot be captured by the scanner, was measured using

Pericardial fat may promote atherosclerosis

Researchers have found more evidence supporting the role of fat around the heart in promoting atherosclerosis, according to a study published online in the journal Radiology.

Study tracks development of chimp brain and makes comparison to humans

In both chimpanzees and humans, portions of the brain that are critical for complex cognitive functions, including decision-making, self-awareness and creativity, are immature at birth. But there are important differences, too. Baby chimpanzees don't show the same dramatic increase in the volume of prefrontal white matter in the brain that human infants do.

Higher protein intake helps postmenopausal obese women lose more weight

Dieting postmenopausal women who want to avoid losing muscle as they lose fat should pay attention to a new University of Illinois study. Adding protein throughout the day not only holds hunger pangs at bay so that dieters lose more weight, it keeps body composition-the amount of fat relative to muscle-in better proportion.

New technique can help scientists rapidly map myelination

Like explorers mapping a new planet, scientists probing the brain need every type of landmark they can get. Each mountain, river or forest helps scientists find their way through the intricacies of the human brain.

Research: 7 Tesla MRI can accurately detect brain scarring linked with epilepsy

Using state-of-the-art, 7 Tesla magnetic resonance imaging (MRI) technology, University of Minnesota Medical School researchers may have uncovered a better approach to diagnosing epilepsy.

Methods for radiation dose optimization in head CT scans

An article in the August issue of the Journal of the American College of Radiology summarizes methods for radiation dose optimization in head computed tomography (CT) scans. Head CT is the second most commonly performed CT examination, with 28 percent of the total number of CT examinations.
