Pitfalls and artifacts of PET-CT in oncologic imaging

초록

Recent technical advances have led to the development of combined positron emission tomography(PET) and computed tomography(CT) scanners. Beyond the vast diagnostic potential associated with the ability to fuse morphologic and functional data, the availability of the CT data enhances the quality of PET. Many potential pitfalls and artifacts have previously been described with 18F-fluorodeoxyglucose PET imaging, but more continue to become apparent as worldwide experience increases. In addition, the advent of combined PET-CT scanners in clinical imaging practice has brought their own specific pitfalls and artifacts. The purpose of this presentation is to learn these potential pitfalls and artifacts so that patients can be optimally prepared for their scans and that accurate interpretation can be made.
