Whole body imaging in the abdominal cancer patient: pitfalls of PET-CT.
Proper interpretation of PET-CT images requires knowledge of the normal physiological distribution of the tracer, frequently encountered physiological variants, and benign pathological causes of FDG uptake that can be confused with a malignant neoplasm. In addition, not all malignant processes are associated with avid tracer uptake. A basic knowledge of the technique of image acquisition is also required to avoid pitfalls such as misregistration of anatomical and scintigraphic data. This article reviews these potential pitfalls as they apply to the abdomen and pelvis of patients with cancer.
