FDG-PET strongest independent predictor of Alzheimer's dementia in MCI

April 8, 2013

PET imaging with 18-fluorodeoxyglucose is the strongest individual positive predictive biomarker of short-term incident dementia in mild cognitive impairment in the most current iterations of Alzheimer’s disease diagnostic criteria, results from a multicenter analysis of 73 patients suggest.

"Since this was a relatively small population of patients, future studies are needed to confirm the results and to assess the incremental diagnostic value and cost-benefit ratio," Dr. Giovanni Frisoni said at the annual meeting of the American Academy of Neurology.
