SSDE strongly depends on the water-equivalent diameter (D W ). In abdominal CT examinations, contrast agent sometimes used to more clearly visualize tissue lesions. Hounsfield unit (HU) images with and without use at specific areas slightly different it may affect D value. This study aimed compare values calculated from axial patients who had undergone routine scans both agent. Axial 144 weight range 3.5 kg 90 using Siemens Sensation 64 scanner were retrospectively collected. automatically Matlab-based IndoseCT (version 15a) software. results show percentage difference between W,contrast W,non - below 2 %. As result, mean 1.5 % smaller than non . Due effect value s %, abdomen can be as accurate Roman","serif"; mso-ansi-language:EN-ID; mso-fareast-language:EN-US;}
