The study was performed with a Discovery LS PET/CT camera (General Electric Medical Systems, Milwaukee, WI). Images were obtained 50 min after intravenous injection of 185 MBq of FDG and performance of CT-based attenuation correction. The acquisition and reconstruction parameters of the FDG-PET scan were 2 min emission/bed, 7 bed position, and iterative reconstruction (subset 14, number of iteration 2). The scanning parameters of the CT were Auto mA (upper limit: 40 mA, noise index 20), 140kV, 5-mm section thickness, 15-mm table feed, and a pitch of 4. The reconstructed images were converted to standardized uptake value (SUV) images with patient’s body weight and injected dose of FDG. The patient had a history of diabetes mellitus and liver cirrhosis with ascites; he had been taking a potassium-holding diuretic, spironolactone, for 8 months. The patient also revealed that he had been experiencing pain and swelling of the bilateral breast for a few months immediately preceding the examination. </p>Thursday, 24 Feb 2011 11:38:45 GMT
