Assessment of Effect dose in CT renal Angiography

Abstract

Computed Tomography (CT) is diagnostic imaging modality giving higher patient dose in comparison with other radiologic procedures, so the calculation of patient dose in CT exam is very significant . CT improved many diagnoses of diseases. The increasing use of CT in Sudan in recent years is consider to motivated the researchers to reduce the exposure of the patient dose and that the risks Known to X-ray. This study aimed to assessing the radiation dose and estimating the risks resulting from exposure to X-ray during CT angiography (CTA) the 64 slice instruments . A total of 50 patient were examined in Alamal National hospital and AlBugaa Diagnostic hospital using spiral CT Scan 64 slices and general electric 16 slices (in the period April 2016-May 2016) The average age of patient samples was(46.4000±14.02621)Years .The main effective dose of renal angiography per procedure was (4.4741±1.28744) msv.The patient will exposed to standard dose during the examine of renal CT angiography .The measurement of the dose during renal procedure can be considered as the best method of evaluation of the cancer risks
