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.
In animal studies, researchers at Johns Hopkins have effectively used magnetic resonance imaging (MRI) to measure with 94 percent accuracy the size and amount of heart muscle damaged by a heart attack, known in medical terms as a myocardial infarct, or m.i., for short.
Using hairlike microelectrodes and computer analysis, neurobiologists at Duke University Medical Center have demonstrated that they can see the detailed instant-to-instant electrical "brainscape" of neural activity across a living brain.
In women with breast lesions that are suspicious for cancer, based on clinical examination or mammography, performing a breast MRI has high sensitivity but only moderate specificity for detecting breast cancer, but does not necessarily eliminate the need for tissue sampling, according to a study in the December 8 issue of JAMA.
Scientists at the Arizona Cancer Center have developed an approach that will allow them to detect if cancer patients are responding within days after they start a new chemotherapy regimen.
Cryotherapy combined with magnetic resonance imaging (MRI) is giving doctors unprecedented control during liver cancer treatment by allowing them to observe the tumors freezing in real time, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
In contrast to people who do not have autism, people with autism remember letters of the alphabet in a part of the brain that ordinarily processes shapes, according to a study from a collaborative program of the National Institute of Child Health and Human Development.
People suffering from paralysis due to stroke or traumatic brain injury may be able to reprogram their brains to improve motor skills and to control artificial limbs, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
When people lie, they use different parts of their brains than when they tell the truth, and these brain changes can be measured by functional magnetic resonance imaging (fMRI), according to a study presented today at the annual meeting of the Radiological Society of North America.
The American Society for Gastrointestinal Endoscopy (ASGE) has reacted with caution to claims of the benefits of computed tomography (CT) colonography, also referred to as virtual colonoscopy, compared to standard colonoscopy.
Neuroscientists at the Farber Institute for Neurosciences at Thomas Jefferson University in Philadelphia will begin a clinical trial testing a new type of drug that attacks amyloid, the protein substance that accumulates in the brains of Alzheimer’s disease patients.
Osteoarthritis (OA) of the knee, a chronic inflammatory disease marked by cartilage degradation and bone abnormalities, is a leading cause of disability among elderly people in the United States.
New findings from researchers at Georgetown University Medical Center in collaboration with Wake Forest University School of Medicine have shown that there is hope for individuals suffering a life-long history of reading problems.
Ever catch a glimpse of someone but can't quite fit a name to go with the face? While it's something that happens to everyone, for older people especially, difficulty in retrieving names is a common frustration.
As well as avoiding metal toilet seats, children who swallow more than one magnet need immediate medical care, according to Alan E. Oestreich, M.D., pediatric radiologist at Cincinnati Children's Hospital Medical Center (CCHMC).
University of Illinois at Chicago researchers are comparing two drugs used to treat pediatric bipolar disorder patients to evaluate how the drugs affect brain function in children with the disorder.
Researchers at the Nanyang Technological University (NTU) Singapore, have developed new computational techniques and algorithms that can allow medical doctors to visualise and assess micro-vessel blood flow in tumours.
Researchers at the Boston Veterans Affairs Health Care System – Brockton Division, Harvard Medical School, and the University of Massachusetts-Boston are using new imaging technology to gather valuable information about the brains of people with schizophrenia.
The U.S. Food and Drug Administration (FDA) today approved the ExAblate 2000 System, a new medical device that uses magnetic resonance image guided focused ultrasound to target and destroy uterine fibroids, non-cancerous masses located in the uterus.
The trial showed that study participants – stroke survivors suffering impaired hand or arm movement – who underwent physical rehabilitation accompanied by motor cortex stimulation showed greater improvement than participants who received physical rehabilitation alone.
Significant changes in the European contrast media and radiopharmaceuticals market are seeing some segments experience growth while others near saturation.
