Four radiologists evaluated the internal and external atrophy of 94 patients into four grades. The CT scans were evaluated three times without measuring procedures in order to determine the inter- and intraobserver variation. In the third evaluation referential scans were used. A considerable inter- and intraobserver variation was experienced. When using referential scans, both inter- and intraobserver variation was reduced to two consecutive grades. In cases where the estimation of atrophy is of specific importance the visual procedure is not reliable.
四位放射科医生将94例患者的内部和外部萎缩情况分为四个等级。对CT扫描进行了三次评估，未采用测量程序，以确定观察者间和观察者内的差异。在第三次评估中使用了参照扫描。观察到观察者间和观察者内存在相当大的差异。使用参照扫描时，观察者间和观察者内的差异均减少到两个连续等级。在萎缩评估具有特殊重要性的情况下，视觉评估程序不可靠。
