Utilization and economic data from head computed tomography (HCT) units providing more than 2 1/2 years' experience are compared with data from installations in 1976. The average unit operates 60 hr/wk, examining 63 patients. Nearly half the examinations are "double" studies, requiring about 53 minutes. The annual total technical cost is approximately $383,000. Charges have been reduced since 1976. While technical charges are lower in high-volume institutions, professional charges are higher. Usual charges and expected net revenues are above Medicare maximum allowable charges. Most units meet the national guidelines. There is considerable variation in data from individual facilities; a "typical" HCT unit cannot be defined.
将拥有超过两年半使用经验的头部计算机断层扫描（HCT）设备的使用情况和经济数据，与1976年安装的设备的数据进行比较。平均每台设备每周运行60小时，检查63名患者。近一半的检查是“双重”检查，大约需要53分钟。年度总技术成本约为38.3万美元。自1976年以来收费已经降低。虽然高流量机构的技术收费较低，但专业收费较高。通常收费和预期净收入高于医疗保险的最高允许收费。大多数设备符合国家指南。各个机构的数据存在很大差异；无法定义一个“典型”的HCT设备。
