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.

Israeli scientists successfully transplant ovaries in sheep and trigger early embryonic development

Israeli scientists report in Human Reproduction that they have successfully transplanted whole frozen and thawed ovaries in sheep, retrieved oocytes from these ovaries and triggered them in the laboratory into early embryonic development.

PET brain scans of a brain chemical messenger system may prove sensitive enough to help plan brain surgery for epilepsy

When drugs fail to control epilepsy, brain surgery is often the only remaining therapeutic option. However, identifying the correct spot for surgery has traditionally required a separate preliminary -- and inherently risky -- surgical procedure.

Smaller prefrontal cortex is associated with early-onset drinking

Previous research has shown that alcohol-use disorders (AUDs) are associated with abnormalities of the prefrontal cortex, thalamus and the cerebellar hemispheres in adults.

First clinical guidelines to help improve the diagnosis and treatment of people with normal pressure hydrocephalus

An international team of medical experts led by a Virginia Commonwealth University researcher has established the first clinical guidelines to help improve the diagnosis and treatment of people with normal pressure hydrocephalus, a debilitating condition in the brain that often goes undiagnosed or is misdiagnosed as Alzheimer's or Parkinson's disease.

Enhanced imaging techniques could improve medical diagnosis

Chris Wyatt is a Virginia Tech electrical engineer who is attempting to provide the medical community with better, quicker, and more relevant images of the human body. The side effects are not bad either - lower medical costs, new treatments, and earlier disease detection.

Safe, non-surgical method of identifying brain infections such as brain abscess

Researchers at Westmead Millennium Institute have discovered a safe, non-surgical method of identifying brain infections such as brain abscess, and an accurate and rapid way of diagnosing meningitis.

When it comes to pain - mind over matter works

According to experts in the U.S., they have strong scientific proof that mind over matter works for relieving pain.

When it comes to controlling pain, positive thinking can be as powerful as a shot of morphine

...according to new brain imaging research at Wake Forest University Baptist Medical Center. Lowering participants' expectations about pain levels reduced both pain-related brain activity and how much pain they felt.

Been there, done that!

One of the neural oddities of "declarative" memory--the recall of past things and events--is that some experiments have shown that recognizing a familiar object is accompanied by a reduction in activity of the brain's memory centers in the medial temporal lobe. Such a reduction seems counterintuitive, since remembering seems to be a positive event.

Blood flow into the brain may play a larger role in the development of dementia than previously believed

Researchers from Leiden University Medical Center in the Netherlands used magnetic resonance imaging (MRI) to examine the brains of elderly patients with and without dementia related to Alzheimer's or Parkinson's disease.

Asthmatics don't need to hear the word "wheeze"

According to a new study, as far as asthmatics are concerned, just the mention of words such as "wheeze" can activate an attack.

Study reveals functional link between emotion processing centers in the brain and certain physiological processes relevant to disease

The mere mention of a stressful word like "wheeze" can activate two brain regions in asthmatics during an attack, and this brain activity may be associated with more severe asthma symptoms, according to a study by University of Wisconsin-Madison researchers and collaborators.

Parts of the brain used in daydreaming are the same areas that fail in people who have Alzheimer's disease

Researchers who used five different medical imaging techniques to study the brain activity of 764 people, including those with Alzheimer's disease, those on the brink of dementia, and healthy individuals, have found that the areas of the brain that young, healthy people use when daydreaming are the same areas that fail in people who have Alzheimer's disease.

MRI helps map smallest deformations inside hearts

Using magnetic resonance imaging technology, or MRI, to tag the work of millions of individual strands of heart muscle fibers, researchers at Johns Hopkins have successfully mapped the smallest deformations inside the beating hearts of 441 middle-aged and elderly men and women who have either silently developed heart disease or remained healthy.

Non-invasive imaging may help predict type 1 diabetes and response to treatment in humans

A key obstacle to early detection of type 1 diabetes - as well as to rapid assessment of the effectiveness of therapeutic intervention - has been the lack of direct, non-invasive technologies to visualize inflammation in the pancreas, an early manifestation of disease.

First clear evidence that olfaction is uniquely a "dual" sense

In the August 18, 2005, issue of Neuron, researchers report that the smell of chocolate activated different brain regions according to whether the odor was introduced into the olfactory system through the mouth or through the nose.

Researchers use diffusion magnetic resonance imaging to monitor ultrasound uterine

Johns Hopkins researchers have, for what is believed to be the first time, used a magnetic resonance imaging (MRI) technique called diffusion-weighted MRI (DWI), a technique that images the movement, or diffusion, of water molecules in tissues, to successfully determine the effectiveness of high-intensity focused ultrasound for treating uterine fibroids.

Scientist have found an unexpected effect of the interaction of PTEN and p53 genes in early stage prostate cancer

Prostate cancer, the second leading cause of cancer death for men in the United States, is caused by changes in several tummor suppressor genes including PTEN and p53. Up to 70 percent of men with prostate cancer have lost one copy of the PTEN gene at the time of diagnosis, and p53 is absent in a high number of patients with advanced prostate cancer.

MediciNova starts phase II clinical trial of MN-166 for multiple sclerosis

MediciNova today announced the enrollment of patients in a Phase II clinical study with MN-166 for the treatment of multiple sclerosis (MS), an inflammatory demyelinating disease of the central nervous system. MN-166 is an orally administered drug with a novel mechanism of action that includes the inhibition of phosphodiesterase IV.

New way to prevent macular degeneration

Two studies from an unusual research partnership at the University of Chicago appear to have resolved a long-standing dispute about the role of melanin in the eye. The studies, one published in the Proceedings of the National Academy of Sciences (PNAS) and one early online in the Journal of the American Chemical Society (JACS), also suggest a new way to prevent a common cause of blindness.
