FDG PET MIP images in two patients who received insulin to reduce blood glucose prior to FDG injection. The first patient received 4 IU insulin because blood glucose was 225 mg/dl (A). Blood glucose reduced to 158 mg/dl. SUVmax/SUVmean and SULmax/SULmean of the liver were 3.6/1.5 and 2.1/0.9, respectively. The second patient received 5 IU insulin because blood glucose was 235 mg/dl (B). The blood glucose reduced to 178 mg/dl. Liver SUVmax/SUVmean and SULmax/SULmean were 1.9/1.2 and 1.4/0.9, respectively. In the 2nd patient there is muscular uptake. Liver activity (visually and SUV) is lower than normal in both patients. The higher difference between SUVmax and SUVmean in the first case as compared to second case may be artefactual. Uptakes in chest lesions are seen in both patients.
