Pitfalls in Positron Emission Tomography/Computed Tomography in the Thorax and Abdomen.

Positron emission tomography/computed tomography (PET/CT) using [18F]-fluoro-2-deoxy-D-glucose (FDG) has become the mainstay imaging modality for evaluating oncology patients with certain cancers. The most common FDG PET/CT applications include staging/restaging, assessing response to therapy and detecting tumor recurrence. It is important to be aware of potential pitfalls and technical artifacts on PET/CT in the chest and abdomen to ensure accurate interpretation, avoid unnecessary intervention and optimize patient care.
