| ScienceDaily (Nov. 16, 2011) -- On the quest for safe, reliable and accessible tools to accurately diagnose Alzheimer's disease, researchers from the Perelman School of Medicine at the University of Pennsylvania found a new way of diagnosing and tracking Alzheimer's disease, using an innovative magnetic resonance imaging (MRI) technique called arterial spin labeling (ASL) to measure changes in brain function. The team determined that the ASL-MRI test is a promising alternative to the current standard, a specific PET scan that requires exposure to small amounts of a radioactive glucose analog and costs approximately four-times more than an ASL-MRI. |
