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.

Combining fMRI and PET scanning creates a way to compare different measurements of the brain's function concurrently

Clinical researchers from the University of Pennsylvania Health System (UPHS) are the first to combine fMRI and PET scanning in radiology, creating a way to compare different measurements of the brain's function concurrently. This analysis could lead to better diagnosis and treatment in patients suffering from brain disorders, like Alzheimer's disease.

Violent video games lead to brain activity pattern that may be characteristic for aggressive thoughts

A Michigan State University researcher and his colleagues have shown that playing violent video games leads to brain activity pattern that may be characteristic for aggressive thoughts.

Electron-beam computed tomography - a more accurate replacement for coronary catheterizations

Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for detecting a dangerous congenital heart abnormality that could cause sudden death, according to research by a Saint Louis University radiologist published last month in Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.

Patients in level I trauma centers were nearly 20 percent less likely to die than those in level II centers

Patients who are taken to a level 2 trauma center after suffering serious injury are significantly more likely to die than comparable patients treated at a major level 1 trauma center, according to researchers at the Keck School of Medicine of the University of Southern California.

Site in the brain that controls language in right-handed people shifts with aging

...a discovery that might offer hope in the treatment of speech problems resulting from traumatic brain injury or stroke.

Minimally invasive needle breast biopsies and sentinel node biopsies should be performed more routinely than they currently are

Physicians should strive to replace traditional, invasive procedures for diagnosing breast cancer with proven, less-invasive diagnostic methods, according to an international panel of breast cancer experts convened at the Keck School of Medicine of the University of Southern California.

Brain abnormalities in people who habitually lie

While previous research has shown that there is heightened activity in the prefrontal cortex - the area of the brain that enables most people to feel remorse or learn moral behavior - when normal people lie, this is the first study to provide evidence of structural differences in that area among pathological liars.

MRI may better enable physicians to plan care for infants with heart defects

Magnetic resonance imaging (MRI) techniques can provide real-time measurements of volume in a fetal heart, and may better enable physicians to plan care for infants with heart defects, according to a new study.

Alcoholics who smoke appear to lose more brain mass than alcoholics who don't smoke

It is already well-known that the brains of long-term alcoholics atrophy and shrink, the study authors say, but the new findings are the first evidence that cigarette smoking might contribute to that atrophy, particularly in grey matter of the parietal and temporal lobes.

Treatment of Nonalcoholic Fatty Liver Disease (NAFLD) in children

The Nonalcoholic Steatohepatitis (NASH) Clinical Research Network has launched its second clinical trial to study NASH, a liver disease that resembles alcoholic liver disease but occurs in patients who drink little or no alcohol. The first trial, launched in January of this year, focuses on adults, while the second trial studies the disease in children.

Still a long way to go in diagnostic evaluation of all patients who suffer ischemic strokes

Women who survive a stroke are less likely than men to get crucial tests of their heart and neck arteries that can help improve their treatment and reduce their risk of a second stroke, a new University of Michigan study finds.

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.
