resonance spectroscopy (MRS), that allows the visualization of biochemical markers that are linked with damage and recovery to the neurons in the brain. The researchers measured biomarkers in the anterior cingulum cortex, a region of the brain assoc...
Different antipsychotic medications may have different effects on brain volume
...ne). Patients underwent neurocognitive testing and magnetic
resonance imaging (MRI) assessments at baseline, and then at 12, 24, 52 and 104 weeks of treatment in a five-year longitudinal study conducted at 14 academic medical centers. A matched sample of 58 healthy volunteers underwent MRI and were compared o...

resonance imaging (fMRI), to examine spirituality and brain patterns. A study of young adults to explore their mental representation of God. They will be asked a range of questions including whether they communicate with a higher being, feel inner...
MR spectroscopy may be superior for determining prostate cancer prognosis
...ians determine the best treatment strategy. Using magnetic
resonance (MR) spectroscopy, which provides detailed information on the chemical composition of tissue samples, researchers from Massachusetts General Hospital (MGH) have shown that chemical profiles of prostate tissue can determine a tumor's prognos...
Learning software developed by Rutgers-Newark scientist helps 450,000 students with reading
...normal reading capabilities showed, via functional magnetic
resonance imaging (fMRI) scans taken in real time, that the brains of the dyslexic children "rewired" themselves during the training, and areas that previously had been inert "lit up" as they were accessed. The brains of the dyslexic children more cl...
Brain imaging study explains Williams syndrome language gifts
...uroscientists led by UCLA researchers used a novel magnetic
resonance imaging (MRI) technique to create the first detailed images showing how Williams syndrome affects the cerebral cortex. The study finds sharply defined cortical thickening and complexity in the area of the brain important to language. Impa...

Rush University Medical Center studies advanced 3D imaging system for radiation therapy
...echnology with his research into the use of strong magnetic
fields may improve the radiation dose distribution. "If we can figure out how to deliver radiation energy concentrated only on the tumor and very little radiation on normal tissue, than all tumors potentially can be destroyed," said Dr. Chu. "We are...
Lipoprotein abnormalities found in severely obese children
...ticles can be measured by a test that uses nuclear magnetic
resonance (NMR) spectroscopy to provide a more detailed lipid profile than standard lipid panels. High-density lipoprotein (HDL) is sometimes called "good" cholesterol because it returns cholesterol to the liver where it can be eliminated. Low-densi...
MRI study shows hormone leptin alters brains, may ease cravings of people with obesity gene
Findings: A magnetic
resonance imaging (MRI) study finds that the protein hormone leptin promotes development of gray matter in the part of the brain that regulates cravings and the ability to monitor personal behavior. After receiving leptin replacement therapy, researc...
The relationship between clinical depression and chronic pain

Combined MRI and mammography more effective at detecting breast cancer in high-risk women
Annual screening, using magnetic
resonance imaging (MRI) and X-ray mammography, is the best way to detect breast cancer in women that have a high genetic risk of the disease, according to a study published online today (Monday May 16, 2005) by The Lancet. Women who have mutations i...
