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

Abstract

Computed tomography (CT), is an x-ray procedure that generates high quality cross sectional images of the body, and by comparison to other radiological diagnosis, CT is responsible for higher radiation dose to patients. The radiation dose was measured in three hospitals in Khartoum state during (April to September 2015) using different CT modalities. In this study, the mean of dose for 64 slice was (924.5±81.12 mGy.cm). The mean of dose for 16 slice (689.1 ±92.5 mGy.cm). The mean of dose in 4 slice was (401.96± 108.3 mGy.cm). The dose is median than that reported in previous studies. The radiation dose higher in Al-zytoun hospital than Al-Fisal and Khartoum hospitals. MSCT scanners 64 slice exposed patients to a higher dose than MSCT scanners16 slice, and MSCT scanners16 slice exposed patients to a higher dose than MSCT scanners 4 slice. The radiologists and CT technologists must be trained to adapt CT scanning techniques based on clinical indications and to assess associated radiation doses with different scanning parameters. The results presented will serve as a baseline data needed for deriving reference doses for KUB examinations in Sudan.
