title: [CT examinations in older age groups].
abstract: A total of 2,878 unselected subsequent CT examinations carried out in 1984 were analyzed retrospectively. All studies were performed in a university hospital with a centralized department of diagnostic radiology. Most of the patients investigated were hospitalized; there were only 12% outpatients. Of the patients studied 12.6% were older than 65 years and 20.5% older than 60; 17.7% were emergency cases and patients between 16 and 25 years of age represented the largest fraction. In all other age groups the relative distribution between emergency cases and regular studies revealed no significant differences. There was no statistically significant difference between the older age group (patients older than 65 years) and the total population of this study in almost all items investigated, i.e., no differences in CT examination time and no differences in preparation time (time between two CT studies). The rate of abdominal CT examinations was 7% higher in the older age group, while the relative distribution of all other CT examinations was again comparable to the total population under study. Thus, the expected increase in patients in the older age group does not measurably prolong the CT examination time. This statement applies to a major referral center with a high percentage of inpatients.
