Evaluation of Radiation Dose for Computed Tomography of Kidney Ureter and Bladder Protocol

Computed Tomography (CT) is a valuable medical imaging technique for the diagnosis of wide range of diseases. Due to development of powerful CT machines, new clinical applications are continue to emerge in medical fields. Study was performed to evaluate dose for patient undergoing Computed Tomography for kidney, ureter and bladder examination. A total of 65 patients were examined in this study. The data collected from three radiology department in Khartoum state from June 2015 to September 2015. The patients were examined with the own department protocol using multislice Computed Tomography four slice, 16 and 64 CT slice Toshiba. The range of patient dose per Computed Tomography procedure was 401.96 mGy. cm to 924.5 mGy. cm. Patient doses showed wide variation due to patient clinical indication, CT system modality and image acquisition parameters. Also there was direct proportionality between the DLP and the mAs. The findings of this study agreed with the results found in the literature. Conclusion The study concluded that DLP & mAs in CT kidney, ureter and bladder procedure are directly proportional to each other.
