Mri

Magnetic resonance imaging (MRI) is a unique and versatile medical imaging diagnostic tool. Using MRI, physicians obtain highly refined images of the body's interior. Strong magnetic fields and pulses of radio waves manipulate the body's natural magnetic, producing images not possible with other diagnostic imaging methods.

Depression uncouples brain's hate circuit
Depression frequently seems to uncouple the brain's "Hate Circuit". The study entitled "Depression Uncouples Brain Hate Circuit" is published in the journal Molecular Psychiatry.

Blast related injuries detected in brains of US military personnel
An advanced imaging technique has revealed that some U.S. military personnel with mild blast-related traumatic brain injuries have abnormalities in the brain that have not been seen with other types of imaging. The abnormalities were found in the brain's white matter, the wiring system that nerve cells in the brain use to communicate with each other.

Chronic low back pain treatment can reverse abnormal brain activity
It likely comes as no surprise that low back pain is the most common form of chronic pain among adults. Lesser known is the fact that those with chronic pain also experience cognitive impairments and reduced gray matter in parts of the brain associated with pain processing and the emotional components of pain, like depression and anxiety.

Researchers at Harvard-affiliated McLean Hospital and the University of Utah have developed the best biologically based test for autism to date. The test was able to detect the disorder in individuals with high-functioning autism with 94 percent accuracy.

Blood flows differently through the brains of schizophrenic patients
Researchers in Germany have used a magnetic resonance imaging (MRI) technique called continuous arterial spin labeling (CASL) to map cerebral blood flow patterns in schizophrenic patients quickly and without using radiation or contrast agents. Their findings appear in the online edition and July printed issue of the journal Radiology.

Men and women respond differently to positive and negative stimuli, revealed by researchers in a study presented at the annual meeting of the Radiological Society of North America (RSNA).

Making imaging procedures safer for patients
The Radiological Society of North America (RSNA) reaffirmed its commitment to patient safety in responding to a study and accompanying perspective on radiation dose from medical imaging procedures in the New England Journal of Medicine (NEJM).

Radiation from medical imaging increasing
Researchers are evaluating the risks and benefits of medical imaging in patients. They revealed that the average effective dose of radiation nearly double the amount they would otherwise be exposed to from natural sources.

Newly diagnosed breast cancer patients and MRI
New research findings published in the August issue of the Journal of the American College of Surgeons challenge the routine use of magnetic resonance imaging (MRI) as a means to improve surgical outcomes in newly diagnosed breast cancer patients.

Prostatectomy effective in men with aggressive prostate cancer
Prostate surgery prostatectomy is found very effective in preventing death in men with aggressive prostate cancers, revealed by researchers at Memorial Sloan-Kettering Cancer Center (MSKCC), Cleveland Clinic and the University of Michigan.

Smoking leads to rapid progression of multiple sclerosis
Patients with multiple sclerosis who smoke appear to experience a more rapid progression of their disease, revealed by researchers in the Archives of Neurology.

Obesity leads to rapid cartilage loss
Obesity is strongly associated with an increased risk of rapid cartilage loss, revealed by researchers at Boston University. The study published in the August issue of Radiology.

Structural MRI may diagnose dementia patients accurately
Researchers developed STAND-Map - a framework for MRI-based differential diagnosis of three common neurodegenerative disorders: Alzheimer's disease, frontotemporal lobar degeneration, and Lewy body disease using Structural MRI.

Routine MRI scan to evaluate breast cancer is challenged
Women with newly diagnosed breast cancer who receive a breast MRI are more likely to receive a mastectomy after their diagnosis and may face delays in starting treatment, revealed by researchers.

Fat to make you feel fuller
Scientists have designed a fatty formulation that can make you feel fuller for longer. When the fat remains stable in the acid environment of the stomach, it empties into the small intestine more slowly and increases satiety.

Meditation may increase gray matter of brain
Push-ups, crunches, gyms, personal trainers - people have many strategies for building bigger muscles and stronger bones. But what can one do to build a bigger brain?

Breast cancer linked to inherited high breast density
A unique mother-daughter study that used magnetic resonance to measure breast density in younger women shows that percent of breast water could be linked to the risk of breast cancer in middle age and older.

New pill cladribine to treat Multiple sclerosis MS
A new drug for multiple sclerosis can dramatically reduce the chances of a relapse or a deterioration of the condition, according to a new study from researchers at Queen Mary, University of London.

Runners clutching bottles of energy drink are a common sight, and it has long been known that sugary drinks and sweets can significantly improve athletes' performance in endurance events. The question is how?

Women with BRCA mutation most likely to undergo mastectomy
Women at increased risk for breast cancer because of the genetic BRCA mutations are more likely to think a prophylactic mastectomy is the best way to reduce their risk for the disease, compared to other women who are at high risk, according to researchers at The University of Texas M. D. Anderson Cancer Center.

MRI wait times to be managed in Canada
A new study headed by Dr. Tom Feasby, Dean of UCalgary's Faculty of Medicine, shows that while Canada lags behind other countries in the number of diagnostic imaging devices, more machines are not the only solution to long wait times.

Physicians should not immediately order routine scans for low-back pain unless they observe features of a serious underlying condition, researchers in the Oregon Evidence-Based Practice Center at Oregon Health & Science University report.

MRI shows signs of multiple sclerosis before disease develops
With more and more people having brain MRIs for various reasons, doctors are finding people whose scans show signs of multiple sclerosis (MS) even though they have no symptoms of the disease.
