Incidental abdominal findings involving the digestive tract have been reported to occur in 1.3% of the scanned patients without significant difference in the intensity of F-FDG uptake w malignant, premalignant, and benign lesions. How focal, fusiform, or lobulated abnormalities are signific more intense than physiological uptake elsewhere i bowel, particularly if associated with a struc abnormality and may sometimes warrant endos examination [4-8]. To the Editor: Incidental pathologic findings h reported on myocardial perfusion scintigraphy as on fluorine-18 fluorodesoxyglucose-positron tomography/ computerized tomography PET/CT) by Kotsalou et al and Bertag respectively and published in HJNM [1-2].
