PET's Targeted Imaging May Lead to Earlier, More Accurate Diagnosis of Dementia and Alzheimer's Disease

Early Diagnosis May Improve Prognosis for Patients, Reports Article in the Journal of Nuclear Medicine

Reston, Va.—Researchers involved in a large, multi-institutional study using positron emission tomography (PET) imaging with the radiotracer fluorodeoxyglucose (FDG) were able to classify different types of dementia with very high rates of success, raising hopes that dementia diagnoses may one day be made at earlier stages.

"Previously, scientists have been able to look only at the surface of the brain to differentiate various types of dementia," said Lisa Mosconi, Ph.D., assistant professor of psychiatry at the New York University School of Medicine. "With FDG PET, we were able to develop standardized disease-specific patterns from which we could correctly classify dementia more than 94 percent of the time."
