Abstract: Hypermetabolic adrenal activity can be seen on F-18 FDG positron emission tomography (F-18 FDG PET) in patients undergoing evaluation for malignancy. The adrenal glands are bilateral organs that are anatomically similar to each other with no differences to arterial supply. They are also a common site of metastases. A retrospective study of 1135 patients with tumors at a veteran hospital was performed to see if hypermetabolic adrenal activity was more common on the left or right. Chi-square analysis demonstrated a significant side preference, with hypermetabolic activity occurring significantly more often in the left adrenal gland.
