Evaluation of Abdomen Computed Tomography Patients' Doses in some Computed Tomography Facilities in South-South and South-East Nigeria

Abstract: This study aimed at the evaluation of administered doses on patients undergoing abdomen computed tomography procedure using the 3.0 version 27/05/2015 of the impact dosimetry software. A total of six computed tomography units were visited but only three were accessed. Within the period of this study ( 14th Aug. 2014 ? 18 Sept. 2015), one hundred and seventy five adults (25 ? 50 years) with body thickness (5.4 ? 7.7kgm-1) were investigated. 93 patients (53.1%) were males and 82 patients (46.9%) were females. The average kVp and mAs used for male and female abdomen computed tomography across the units were (kVp =120.3 and mAs =117.1) and (kVp =120.0 and mAs =116.9) respectively. The maximum average effective dose for abdomen computed tomography were obtained for male and female at computed tomography center (Y) as (male = 7.54mSv) and (female = 8.86mSv) respectively, while the minimum is at computed tomography centre (Z) as (male = 1.9mSv) and (female = 2.7mSv) respectively. The average organ doses were obtained and recorded. The results obtained were compared to other similar studies within and outside Nigeria. Some varying effects such as gender, patient?s body thickness, exposure factors (kVp and mAs) and dose indicators (CTDI) were noted.
