- Abstract
This work aimed to analyze the effective doses radiation, estimated from the dose-length product, in 4821 examinations carried out in three CT scanners (named as A, B and C) during the period of December 1st 2013 to 30th November 2014 and compare them, with 95% confidence interval, with typical values for the CT practice described in the American Association of Physicists in Medicine (AAPM) Report # 96 (2008). The mean values of effective doses found in the A, B and C equipments were, respectively, 1.55, 2.09 and 1.30 mSv, in head; 7.75, 9.01 and 10.45 mSv in abdomen/pelvis; and 3.87, 7.94 and 3.92 mSv in chest examinations. There were significantly different among each service, except between the A and C equipments in the chest examinations (p = 0.7148). Only the B equipment performed CT scans with effective doses above the US typical values, for head and chest examinations.
