Fig. 2From: 18F-FDG PET/CT image findings of a dog with adrenocortical carcinomaFused positron emission tomography/computed tomography images using 18F-fluorodeoxyglucose in a dog with adrenocortical carcinoma. a Increased 18F-fluorodeoxyglucose uptake of the peripheral region of the right adrenal mass (an arrow head) was observed and central region of the mass revealed necrosis in dorsal plane, b Region of the interest (ROI) was drawn in transverse plane for adrenal mass. Maximal standardized uptake value (SUV) is 3.24 and mean SUV is 0.36. c ROI was drawn in transeverse plane for peripheral region of the adrenal mass. Mean SUV is 0.79. d ROI was drawn in transeverse plane for liver. Mean SUV is 0.62. Relative SUV (adrenal SUVmax/liver SUVmean = 3.24/0.62) is 5.23Back to article page
