MRI technique distinguishes between Alzheimer's and frontotemporal dementia
July 12th, 2005
A non-invasive magnetic resonance imaging (MRI) technique called arterial spin labeling is just as accurate as invasive scanning techniques in distinguishing Alzheimer's disease from frontotemporal dementia (FTD) in the brains of elderly people, according to a new study at the San Francisco VA Medical Center (SFVAMC). The study, led by Norbert Schuff, PhD, a principle investigator at SFVAMC, used arterial spin labeling to measure perfusion, or blood flow, in the areas of the brain affected by the two diseases. "Blood flow indicates brain activation," said Dr. Schuff. "So the area with less blood flow is the area affected by disease." In the study, arterial spin labeling...
