The authors studied the influence of computed tomography (CT) on radiologic utilization in The Netherlands. Twenty-six hospitals with a CT scanner were compared with 27 hospitals without on the basis of number of radiologic procedures per clinical patient from 1977 to 1984. Changes in average length of hospitalization were also considered. The number of procedures decreased in hospitals with CT scanners (-9%), in contrast to hospitals without (+10%). The influence of CT on average length of stay appeared minimal. Although this study was limited, the authors believe that use of CT influenced changes in radiologic utilization.
作者们研究了计算机断层扫描（CT）对荷兰放射学应用的影响。将拥有CT扫描仪的26家医院与没有CT扫描仪的27家医院，基于1977年至1984年每位临床患者的放射学检查程序数量进行了比较。还考虑了平均住院时间的变化。拥有CT扫描仪的医院检查程序数量减少了（-9%），相比之下没有CT扫描仪的医院则增加了（+10%）。CT对平均住院时间的影响似乎很小。尽管这项研究存在局限性，但作者们认为CT的使用影响了放射学应用的变化。
