Abstract
Introduction:Intravenous urography (IVU) test includes high number of images and extended imaging size. These make IVU as a diagnostic method with high absorbed doses by sensitive organs such as intestine and gonads in pelvic-abdominal area. In this study absorbed doses of pelvic-abdomen sensitive organs such as Adrenal, Bladder, Colon and Gonads in IVU test. Method and Materials: Demographic properties of one hundred patients’ who referred for kidney imaging was recorded during one year. Exposure factors were recorded for each patient during IVU test. In this study CALDose software used for Entrance Surface Air Kerma (ESAK) recording. Organ dose was calculated by conversion coefficient of organ × ESAK Results: The age averages of men and women were 52 and 53 years, respectively. The average ESAK dose for patients in one step of each IVU examination was 3.8 mGy. The organ dose of Adrenal, Bladder, Colon and Gonads 1.8, 1.8, 7.0 and 2.0, respectively. Conclusion: These results showed that IVU processing in clouding higher dose to sensitive organs and selection of correct exposures factors can reduce organ dose.
