Unexpected focal fluorodeoxyglucose uptake in main organs; pass through or pass by?

Figure 2 Multiple foci of physiological fluorine-18 fluorodeoxyglucose uptake. Images of a 79-year-old woman diagnosed with pancreatic body cancer. A: Focal uptake is observed in the right lower abdomen (arrow); B: Suspicious uptake as a lesion; C: No lesion but right ureter. Multiple hypermetabolic areas are observed along the descending and sigmoid colon in image A. Colonoscopy found nothing abnormal, and the uptake is probably due to normal physiological uptake.
