All of these patients underwent DE-CT imaging with tube voltages of 80 kVp and 140 kVp within two weeks before surgery. Mean attenuation values were measured for every GB polyp at 80\/140 kVp and at 40\/140 keV. The mean attenuation value changes between 140 kVp and 80 kVp (MAVC\n 140\u201380 kVp<\/jats:sub>\n ) and mean attenuation value changes between 100 keV and 40 keV (MAVC\n 100\u201340 keV<\/jats:sub>\n ) were calculated.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The CT image parameters of all 46 patients with GB polyps were analyzed.
