We sought to estimate the radiation dose and associated exposure parameters in the multiphase abdomen -pelvic scan of Multidetector Computed Tomography (MDCT) studies in clinical practice. This was a retrospective cross sectional study describing radiation dose associated with main exposure parameters in diagnostic multiphase abdomen -pelvic scans performed on 152 consecutive patients by two different sixteen (16) slice CT scanners. Patient information, exposure parameters of CTDI (volume) , DLP, kVp, mAs and pitch were recorded for every phases of abdomen-pelvic study from dose report of MDCT scanners. Patient age range from 18 to 87 years. Overall CTDI (volume) median was 63.8 (±10.4)mGy for multiphase abdominal-pelvic scan with scanner A while it was 35.4 (±15.6)mGy for scanner B. Effective dose for patients in multiphase abdomen -pelvic CT scan range from 8.2 mSv to 58 mSv. Median effective dose for patients, who underwent multiphase abdomen-pelvic scan with scanner A and B were 38.5 (± 8.2) mSv and 21.3 (± 8.6) mSv respectively. Median value of exposure parameters of mAs, kVp and pitch were 150 (±29.7), 130 (±15.3) and 1.3 (±0
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
