title: Utilization of head computed tomography units: in installations with greater than two-and-a-half years' experience.
abstract: 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.
