Technical considerations in brain amyloid PET imaging with 18F-Florbetapir

Abstract

Technical factors play a critical role in the production of best-quality amyloid PET images for interpretation. This article provides specific instructions and general technical information about PET brain scanning of ß-amyloid neuritic plaques. The focus of tracer-specific information will be on 18F-florbetapir (indications, contraindications, dosing, administration, uptake time, scanning time, acquisition, processing, biodistribution, radiation dose, adverse events, and display). General scanning information relevant to all amyloid-imaging agents will be also be presented (e.g., mechanism of uptake, safe handling, positioning, prevention of patient motion, processing, and artifacts).
