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.

Treating sleep apnea with continuous positive airway pressure reduces incidence of stroke

Patients with moderate to severe sleep apnea who have significantly higher serum levels of inflammatory markers that serve as precursors to coronary artery disease, as well as lesions associated with silent brain infarction, have an elevated risk of stroke, according to a group of Japanese medical researchers.

FDA approves Elbit software for use with uterine fibroid treatment

Israel-based Elbit Medical Imaging on Monday said that FDA has approved software that aims to reduce treatment time for the uterine fibroid device ExAblate 2000, the AP/Forbes reports.

Targeted nanoparticles image early tumors

A well-established fact in cancer therapy is that early tumor detection improves the odds that a patient will survive the disease. Now, using nanoparticles targeted to the tiny blood vessels that surround even the smallest tumors, researchers at the Siteman Center for Cancer Nanotechnology Excellence (CCNE) have developed a radioactive imaging agent that was able to identify human tumors in rabbits.

Single-slice magnetic resonance imaging reveals 'hidden' fat that puts adolescents at risk for disease

According to a new study featured in the March issue of Radiology, single-slice magnetic resonance imaging (MRI) is a fast, non-invasive way to measure intra-abdominal fat, which when excessive, may put children and teenagers at risk for developing heart disease, diabetes and other illnesses.

Reduced brain growth in alcoholics with family drinking history

The brains of alcohol-dependent individuals are affected not only by their own heavy drinking, but also by genetic or environmental factors associated with their parents- drinking, according to a new study by researchers at the National Institute on Alcohol Abuse and Alcoholism (NIAAA).

Scientists label cells with magnetic nanoparticles

Investigators at the German Cancer Research Center have developed silica-coated iron oxide nanoparticles that allow for cell tracking in a live animal using magnetic resonance imaging (MRI).

Sharper MRI's

Magnetic resonance imaging, or MRI, has revolutionized health care, providing doctors with a highly accurate, non-invasive tool for diagnosing cancer, injuries and other maladies within the human body. Now, a Florida State University researcher has collaborated in a research project that could lead to ways of producing even sharper medical images.

Changes in breast cancer management

Aggressive research currently underway brings hope of dramatic advances in breast cancer management, according to a new review.

Back regions of the brain, which control vision, grow significantly faster than prefrontal region in newborns

The regions of the brain that control vision and other sensory information grow dramatically in the first few months following birth, while the area that controls abstract thought experiences very little growth during the same period, University of North Carolina at Chapel Hill researchers have found.

New type of nanoparticle created by spray pyrolysis

Researchers at the University of California, Davis, have created a new type of nanoparticle that could be used in tests for medical diagnostics, environmental pollution, and contamination of food products.

Damage to muscle during vaginal deliveries connected with pelvic organ prolapse

An increase among women electing to have caesarean sections in recent years has been due in large part to a concern that giving birth vaginally will lead to a fallen bladder and uterus in later life, and the issue has been hotly debated in the medical community.

One in four normal births cause brain hemorrhages in babies

Researchers in the United States have found that many babies who were delivered vaginally, experience bleeding in and around the brain shortly after birth.

Giving birth to a child naturally increases risk of hemorrhage in newborns

The first researchers to use magnetic resonance imaging (MRI) to study the brains of a large group of babies soon after birth found a small amount of bleeding in and around the brains of one in four babies who were delivered vaginally.

Design of gold nanoparticles for magnetic resonance imaging

Molecular complexes containing the element gadolinium are proven agents for increasing the diagnostic utility of magnetic resonance imaging (MRI), but their use in detecting small tumors is limited by the relatively weak signal these agents produce.

Link between MRI contrast agent and nephrogenic systemic fibrosis

New research has shown a possible association between a popular magnetic resonance imaging (MRI) contrast agent and the incidence of a rare disease called nephrogenic systemic fibrosis (NSF) in patients with kidney disease, according to an editorial appearing in the March issue of Radiology.
