PET/CT in the thorax: pitfalls

Radiol Clin North Am. 2014 Jan;52(1):17-25. doi: 10.1016/j.rcl.2013.08.005. Epub 2013 Sep 11.

Abstract

PET/CT is widely used in the staging and assessment of therapeutic response in patients with malignancies. Accurate interpretation of PET/CT requires knowledge of the normal physiologic distribution of [18F]-fluoro-2-deoxy-d-glucose, artifacts due to the use of CT for attenuation correction of the PET scan and potential pitfalls due to malignancies that are PET negative and benign conditions that are PET positive. Awareness of these artifacts and potential pitfalls is important in preventing misinterpretation that can alter patient management.
