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.

Autism may be evident in an infant’s brain much earlier than thought: Study

Researchers have found that autism shows tell tale signs in babies as young as 6 months old — half a year or more before parents typically begin to notice symptoms of the condition. The results shed light on the fundamental differences in the brains of autistic children and could help lead to earlier detection and treatment, says co-author Geraldine Dawson, chief science officer at Autism Speaks, which helped fund the study in today's American Journal of Psychiatry.

OICR launches Phase III Active Surveillance Magnetic Resonance Imaging Study Trial

Dr. Nicole Onetto, Deputy Director and Chief Scientific Officer of the Ontario Institute for Cancer Research (OICR), today announced the launch of an innovative Phase III clinical trial that aims to determine whether multi-parametric magnetic resonance imaging (MRI) coupled with transrectal ultrasound (TRUS) guided biopsy (called fusion technology) can accurately identify men with prostate cancer who are at risk of developing aggressive disease.

In young children autism does not appear suddenly, but develops over time

A new study led by the University of North Carolina at Chapel Hill found significant differences in brain development starting at age 6 months in high-risk infants who later develop autism, compared to high-risk infants who did not develop autism.

Diffusion-weighted MRI may effectively indicate response to ovarian cancer treatment

Cancer Research UK-funded scientists have determined that a magnetic resonance imaging (MRI) technique, which measures the movement of water molecules within the tumour, may be the best way to monitor how women with late-stage ovarian cancer are responding to treatment. The study is published in the journal Radiology today.

MRI techniques can measure changes in microstructural properties of white matter

Innovative magnetic resonance imaging (MRI) techniques that can measure changes in the microstructure of the white matter likely to affect brain function and the ability of different regions of the brain to communicate are presented in an article in the groundbreaking new neuroscience journal Brain Connectivity, a bimonthly peer-reviewed publication from Mary Ann Liebert, Inc.

Lawson Health Research Institute receives new hybrid imaging scanner

Imagine being able to detect Alzheimer's disease at its earliest stage and prescribe the proper medication to halt its progress. Imagine being able to evaluate the health of heart muscles and tissues after an attack and accurately prescribe treatment to prevent future heart failure. London is close to making these possibilities a reality with the installation of Canada's first whole body PET/MRI scanner at St. Joseph's Hospital, part of St. Joseph's Health Care London.

Study may explain why women have higher rate of ACL injuries than men

Much orthopaedic research has been devoted to determining why women are far more susceptible to knee ligament injuries than men. According to a new study, the answer may lie in geometry - the length and shape of a patient's knee bone - more than gender.

Preliminary results from Remedy Pharmaceuticals' RP-1127 Phase 2 trial on stroke

Each year, over 700,000 people in the United States suffer a stroke. For most, medical science can do very little. Some will die; a number will suffer debilitating aftereffects. Now, preliminary results of a Phase 2 clinical trial using Remedy Pharmaceuticals' new drug, RP-1127, presented at the 2012 International Stroke Conference in New Orleans on February 2, offer hope to many of these patients.

MRI shows elevated BMI linked to greater extent and severity of degenerative disc disease

One of the largest studies to investigate lumbar spine disc degeneration found that adults who are overweight or obese were significantly more likely to have disc degeneration than those with a normal body mass index (BMI).

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.

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.
