Cerebral amyloid can be quantified using F-18-Florbetapir positron emission tomography (PET) which has been shown in postmortem investigations to have a highly significant correlation with β-amyloid plaque deposition, making this a reliable quantitative marker of amyloid load in the human brain. 1 Semiquantitative Florbetapir PET has been shown to have up to an 88% sensitivity and 81% specificity for AD. 2 Semiquantitative assessments of Florbetapir uptake
