PET/CT Imaging: Patient Instructions and Preparation
18F-FDG PET is a frequently used imaging modality in the evaluation of cancer patients. A high-quality study performed 18F-FDG PET study should be repeatable (same result produced if imaged on the same system) and reproducible (similar result if imaged at different sites). An essential component of this is adequate patient preparation to ensure study reproducibility and technical quality. Rigorous instructions should be followed regarding patient procedure. In addition, adequate referral information is important so that the correct timing of study and imaging protocol can be followed, e.g. lung gating for a base of lung lesion. This section addresses some of these issues, and summaries of required clinical information, patient preparation, procedure and imaging parameters are shown in Tables 7.1, 7.2 and 7.3.
