Evaluating the relationship between Quality Assurance and Exposure Level for Head and Abdomen Computed Tomography Procedures in a selected Kenyan Hospital

This research aimed at evaluating the relationship between a scanner’s operating conditions and the exposure levels for head and abdomen procedures to a 64-slice Multi-Detector Computed Tomography, and for radiological compliance. The Quality Assurance of the scanner was assessed using two-part phantoms for acceptance tests by International Electro-Technical standards. Significant discrepancies between the machine and measured CTD$\mathrm{I}_{\mathrm{v}\mathrm{o}\mathrm{l}}$ were detected. The percent Coefficient of Variation (% CV) for the exposure parameters (CTD$\mathrm{I}_{\mathrm{w}}$, DLP, and ED) varied between 7.1 to 75% as compared to EC guidelines. To reduce patient radiation exposure and achieve clinical accuracy, institutional DRLs should be established for radiological compliance.
