Abstract

CT has been an integral part of hybrid imaging PET/CT and SPECT/CT for almost two decades and has not received the attention it deserves when compared to PET or SPECT. As the sensitivity and reconstruction of a PET scanner were improved over the years, the amount of radiation from the injected 18F-FDG dose to the patient was decreased and the radiation dose of CT often times superseded the radiation from the injected 18F-FDG dose. Today, many clinics may have a larger portion of radiation dose from CT than from 18F-FDG in a PET/CT scan if they use the vendor’s default CT protocol. Understanding CT can help lower the radiation exposure of CT, and can help improve localization and quantitation of functional PET or SPECT imaging. This chapter covers the essential knowledge of CT to excel the applications of PET/CT and SPECT/CT.
