الملخص

The aim of this study to estimate the radiation dose received by the patients during abdomen CT examinations. A total of 60 adult patients undergoing abdominal CT scanning exams were estimated using CTDIvol, dose length product (DLP) and effective dose (E) and evaluate effective dose and organs dose by using CT expo version 2.5 software.Also this study revealed that the mean effective dose for abdomen in hospital (A), hospital (B) and hospital (C) was (7.6)mSv, (5.3) mSv and (6.3) mAs respectively. The mean of DLP for in hospital (A), hospital (B), and hospital (C) was (450) mGy*cm, (410.95) mGy*cm and (380) mGy*cm respectively. The mean CTDIvol for abdomen in hospital (A), hospital (B) and hospital (C) was (9.9) mGy, (8.8) mGy and (7.3) mGy respectivelyThe result of this study revealed that the mean equivalent dose for abdomen organs, stomach was (12.23) mSv, spleen was (11.99) mSv, pancreas was (9.8) mSv and adrenal gland was(9.158) mSv.And the organ doses were estimated using measurements of CT dose indexes (CTDI), exposure-related parameters, and the ImPACT spreadsheet based on NRPB conversion factors. Light variation of organ doses among three hospitals was observed for similar CT examinations. These variations largely originated from different CT scanning protocols used in different three hospitals. The organ doses in this study
