Abstract
The objective of this study was to calculate the effective radiation dose to patients undergoing barium enema. Participants were 200 patients who underwent barium enema at the Osaka Center for Cancer and Cardiovascular Disease Prevention from April 1 to December 28, 2005. The dose-area products of the fluoroscopy dose, imaging dose, and total dose for each examination using a computed radiography digital X-ray television fluoroscopy system were calculated. The effective dose was obtained by inputting the average value of the dose-area products into Monte Carlo simulation software. The results showed that the effective dose was 5.12 mSv for fluoroscopy and 4.43 mSv for radiography. Therefore, the effective dose to the patient in barium enema was 9.55 mSv.
