Abstract
ABSTRACTThe growth in the usage of CT scanners in Australia between 1994 and 2002 is reviewed. The parallel growth in the per caput dose from CT procedures is derived by first estimating the mean dose for broad categories of Medicare Benefits Schedule procedures and then applying these estimates to counts of the number of procedures in each category. It is estimated that the annual dose per capita from CT procedures has increased from about 0.37 mSv in 1994 to about 0.9 mSv in 2002. From 1994–2002 the growth in CT usage has been mainly amongst adults over 35 years of age while usage amongst infants in the 0–4 year age group has remained within 10% of that in 1994.
