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.

Researchers develop new MRS technique to diagnose brain tumors

Researchers at UT Southwestern Medical Center have developed what they believe to be the first clinical application of a new imaging technique to diagnose brain tumors.

Scientists evaluate growth, differentiation and function of iPSC-derived NPCs in PD

Induced pluripotent stem cells (iPSC) are a promising avenue for cell replacement therapy in neurologic diseases. For example, mouse and human iPSCs have been used to generate dopaminergic (DA) neurons that improve symptoms in rat Parkinson's disease models. Reporting in the current issue of the Journal of Parkinson's Disease, a group of scientists from Japan evaluated the growth, differentiation, and function of human-derived iPSC-derived neural progenitor cells (NPCs) in a primate model, elucidating their therapeutic potential.

Magic Mushroom’s compound may help in some mental disorders: Study

There has been little research on the mechanism of action of “magic mushrooms” on the brain. A growing number of studies suggested that perhaps the mushrooms' key ingredient could work magic for certain mental disorders. New research in Proceedings of the National Academy of Sciences sheds light on why one of the mushrooms' hallucinogenic chemical compounds, psilocybin, may hold promise for the treatment of depression.

Possible link between vascular lesions and Alzheimer's disease

Approximately 20 percent of all stroke survivors will develop cognitive problems later in life, including vascular dementia. Experts with the Methodist Neurological Institute in Houston say recent research showing a possible link between vascular lesions and Alzheimer's disease is yet another reason to be more vigilant in our efforts to prevent a stroke.

A*STAR, GE Global Research join forces in integrated advanced medical imaging technologies

GE Global Research, the central technology development arm for GE Healthcare and all of GE's businesses, has signed a Memorandum of Understanding (MOU) with Singapore's Agency of Science, Technology and Research (A*STAR). This agreement will focus on advancing current medical imaging technologies and diagnostics to enable more accurate, earlier and faster clinical diagnoses of cancer and other diseases. The partnership between A*STAR and GE Global Research brings together two world-class research institutions, integrating their deep domain expertise in biomedical, science, and engineering capabilities to support this effort.

Traditional autopsy is still the gold standard in determining cause of death

TV crime shows like Bones and CSI are quick to explain each death by showing highly detailed scans and video images of victims' insides. Traditional autopsies, if shown at all, are at best in supporting roles to the high-tech equipment, and usually gloss over the sometimes physically grueling tasks of sawing through skin and bone.

Article summarizes methods for radiation dose optimization in pediatric CT scans

An article in the January issue of the Journal of the American College of Radiology summarizes methods for radiation dose optimization in pediatric computed tomography (CT) scans.

Working Group recommends use of biomarkers in AD clinical trials

A group of thought leaders in Alzheimer's disease says the science is solid and the time has come for more widespread use of biomarkers in Alzheimer disease (AD) clinical trials, to speed the identification of effective disease-modifying treatments for this incurable disorder.

RNF123 gene may play a role in major depression

Psychiatric disorders can be described on many levels, the most traditional of which are subjective descriptions of the experience of being depressed and the use of rating scales that quantify depressive symptoms. Over the past two decades, research has developed other strategies for describing the biological underpinnings of depression, including volumetric brain measurements using magnetic resonance imaging (MRI) and the patterns of gene expression in white blood cells.

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.
