Evaluation of Computed Tomography Doses in Patients in Selected Facilities in South-South and South-East Regions Nigeria

In this study, we evaluates the mean organ dose using imPACT software and compare the patient doses obtained with values from other international studies findings done with similar software. Seven Computed Tomography (CT) facilities were carefully selected in the south-south and southeast region of Nigeria. An imPACT Patient Dosimetry Calculator Software was used to determine organ dose to the head, chest, abdomen and pelvic region from 359 patients' CT parameters retrieved from the CT monitor. Data analysis was done using (T-test) Olivia et al (2011). Significant differences exist in similar organ doses among the 7 CT units selected in south-south and southeast indicating that there was harmonization in CT protocols considered.
