Positron emission tomography (PET) has become an integral part of the management of patients with cancer as well as some cardiac and neurological diseases. 18F-fluorodeoxyglucose (FDG) PET is commonly used to stage cancer patients after initial diagnosis, but is increasingly used at other points in the patient's management, including the assessment of treatment response and detecting recurrent disease. In common with most imaging techniques there are pitfalls in interpretation of PET and PET/computed tomography (CT) studies. Many potential pitfalls and artefacts have previously been described with 18F-FDG PET imaging, but more continue to become apparent as worldwide experience increases. ⋯ It is important that referring clinicians, PET/CT interpreters and imaging technologists/radiographers are aware of potential pitfalls so that their impact is minimised and that the image data are acquired and interpreted in the most accurate manner. With careful patient preparation, attention to detail and adequate training, the se artefacts and pitfalls may be minimised allowing this powerful hybrid imaging technique to realise it's potential. This paper attempts to describe some of the common pitfalls and artefacts and how they can be avoided or appropriately interpreted.

Comparative StudyTwo-dimensional vs three-dimensional imaging in whole body oncologic PET/CT: a Discovery-STE phantom and patient study.
To evaluate the performance of the positron emission tomography (PET)/computed tomography (CT) Discovery-STE (D-STE) scanner for lesion detectability in two-dimensional (2D) and three-dimensional (3D) acquisition. ⋯ In oncological applications, the D-STE system demonstrated good performance in 2D and 3D acquisition, while 3D exhibited better image quality, data accuracy and consistency of lesion detectability, resulting in shorter scan times and higher patient throughput.
