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.

MTR technique indicates that COPAXONE therapy results in tissue repair in RRMS patients

Researchers utilizing an advanced magnetic resonance imaging (MRI) technology to characterize and chart the evolution of MS lesions found that relapsing-remitting multiple sclerosis (RRMS) patients treated with COPAXONE (glatiramer acetate injection) experienced significantly increased magnetization transfer ratio.

Adolescents diagnosed with schizophrenia appear to show greater brain GM volume loss

Adolescents diagnosed with schizophrenia and other psychoses appear to show greater decreases in gray matter volume and increases in cerebrospinal fluid in the frontal lobe compared to healthy adolescents without a diagnosis of psychosis, according to a report in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Radiology researchers discover that MS affects thalamus of the brain

Radiology researchers at The University of Texas Health Science Center at Houston (UTHealth) have found evidence that multiple sclerosis affects an area of the brain that controls cognitive, sensory and motor functioning apart from the disabling damage caused by the disease's visible lesions.

TAU researcher develops capsule endoscope to investigate digestive system

Endoscopes - small cameras or optic fibres that are usually attached to flexible tubing designed to investigate the interior of the body - can be dangerously invasive. Procedures often require sedative medications and some recovery time. Now a researcher at Tel Aviv University is developing a "capsule endoscope" that can move through the digestive tract to detect problems independent of any attachments.

Decision support tool for objective diagnostics of Alzheimer's

European PredictAD project, lead by Principal Scientist Jyrki Lötjönen from VTT Technical Research Centre of Finland, has developed a decision support tool for objective diagnostics of Alzheimer's disease.

MRI can predict breast cancer prognosis

Quantitative magnetic resonance imaging measures were associated with prognostic tumor markers, demonstrating the potential of magnetic resonance imaging for prediction of disease prognosis and stratification of patients to appropriate therapies, according to preliminary data presented at the 2011 CTRC-AACR San Antonio Breast Cancer Symposium, held Dec. 6-10, 2011.

Autism linked with disorganized structure of brain's white matter

It's still unclear what's different in the brains of people with autism spectrum disorders (ASDs), but evidence from genetic and cell studies points to abnormalities in how brain cells (neurons) connect to each other. A study at Children's Hospital Boston now provides visual evidence associating autism with a disorganized structure of brain connections, as well as defects in myelin -- the fatty, insulating coating that helps nerve fibers conduct signals and that makes up the brain's white matter.

Yale researchers monitor growth of laboratory-engineered blood vessels after implantation

Using magnetic resonance imaging (MRI) and nanoparticle technology, researchers from Yale have devised a way to monitor the growth of laboratory-engineered blood vessels after they have been implanted in patients. This advance represents an important step toward ensuring that blood vessels, and possibly other tissues engineered from a patient's own biological material, are taking hold and working as expected.

Repeated soccer headers could lead to brain damage: Study

A new study suggests that frequent “heading” of soccer balls by avid amateur players may cause brain damage leading to subtle but serious declines in thinking and coordination skills.

Study finds structure-function impairments in people addicted to cocaine

The more gray matter you have in the decision-making, thought-processing part of your brain, the better your ability to evaluate rewards and consequences. That may seem like an obvious conclusion, but a new study conducted at the U.S. Department of Energy's Brookhaven National Laboratory is the first to show this link between structure and function in healthy people - and the impairment of both structure and function in people addicted to cocaine.

Phillips gets FDA approval for its combo PET/MRI scanner

Royal Philips Electronics NV has received approval from U.S. regulators to introduce a single medical imaging device that can scan the body for cancer using two technologies.

Virtual childbirth software can help plan majority of C-sections

Newly developed computer software combined with magnetic resonance imaging (MRI) of a fetus may help physicians better assess a woman's potential for a difficult childbirth. Results of a study using the new software were presented today at the annual meeting of the Radiological Society of North America (RSNA).

Study uses MRI to evaluate cardiovascular risk in WTC first responders

In the first study using magnetic resonance imaging (MRI) to evaluate cardiovascular risk in World Trade Center (WTC) first responders, researchers from Mount Sinai School of Medicine have found that the responders who experienced high levels of exposure to the initial dust cloud on September 11, 2001, demonstrate high-risk features of atherosclerosis.

Experimental drug selectively destroys blood supply of fat tissue and decreases body fat

Obese rhesus monkeys lost on average 11 percent of their body weight after four weeks of treatment with an experimental drug that selectively destroys the blood supply of fat tissue, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports in Science Translational Medicine.

Study: Children with autism have more prefrontal brain neurons

In a small, preliminary study that included 13 male children, those with autism had an average 67 percent more prefrontal brain neurons and larger than average brain weight, than children without autism, according to a study in the Nov. 9 issue of JAMA.

Study finds spinal bleeding in young children with abusive head trauma

A new study found that spinal bleeding is found often in young children who are victims of abusive trauma. The findings support performing complete spine imaging for children undergoing brain magnetic resonance imaging (MRI) for moderate or severe traumatic brain injury and suggest a pathway for distinguishing between abusive and accidental injury.
