Preop MRI to measure CBF may benefit neonates with heart defects
By Shalmali Pal
Advances in neonatal cardiac surgery have vastly improved newborn survival rates, but impaired neurodevelopment and neurological damage remain major concerns in these high-risk patients. Researchers from Philadelphia have found that using MRI to measure cerebral blood flow in severe cases of congenital heart defects may identify a preoperative risk factor for poor neurocognitive outcome.

PET, SPECT show MMSE to be poor prognosticator of Alzheimer's
By Jonathan S. Batchelor
The Mini-Mental State Examination (MMSE) is widely used to assess the severity of dementia. But in comparing MMSE scores with PET and SPECT results of Alzheimer's patients, researchers from the University of Kansas Medical Center found that the MMSE poorly predicted the severity of imaging results, and that evaluating dementia with PET and SPECT may hasten Alzheimer's diagnoses.

MRI may determine which stroke-infarcted brain tissue is salvageable
By Eric Barnes
CHICAGO - In acute stroke patients, the decision to give thrombolytic therapy is a crudely calculated risk: Will tPA salvage infarcted but still-living tissue -- or merely heighten the patient's risk of bleeding? Researchers at Massachusetts General Hospital in Boston are hoping to demystify this leap of faith based on a technique that helps gauge the status of the individual infarct when therapy is being considered.

MRSI may be just the "tool" to diagnose bipolar disorder
CHICAGO - Patients with bipolar disorder are often undiagnosed or misdiagnosed for years. But preliminary research suggests that magnetic resonance spectroscopy imaging (MRSI) may take the guesswork and delay out of diagnosis, according to Dr. John D. Port, Ph.D., assistant professor of radiology at the Mayo Clinic in Rochester, MN.
