PET Amyloid Ligand [<sup>11</sup>C]PIB Uptake and Cerebrospinal Fluid β-Amyloid in Mild Cognitive Impairment

Abstract

Follow-up studies are needed to confirm whether [(11)C]PIB uptake might be more sensitive than CSF Abeta42 concentration in detecting increased amyloid burden in MCI, as suggested by the results of this study.
