Abstract

This study attempts to assess the impact of computerized cranial tomography (CT) on clinical practice in a veterans hospital. A CT scan could be performed only if there existed a reasonable potential for the results to affect the patient's clinical course. We document many instances of how the 163 CT scans obtained during a one-year period aided patients. We quantitated one beneficial aspect by estimating the major neuroradiologic contrast procedures obviated by CT scan. Case-by-case review indicates 70 cerebral arteriograms and 58 pneumoencephalograms would have been performed had CT scanning not been available.

摘要

本研究试图评估计算机断层扫描（CT）对一家退伍军人医院临床实践的影响。只有当结果有合理的可能性影响患者的临床病程时，才会进行CT扫描。我们记录了在一年期间获得的163次CT扫描对患者有帮助的许多实例。我们通过估计CT扫描避免的主要神经放射造影程序来量化一个有益的方面。逐案审查表明，如果没有CT扫描，将会进行70次脑血管造影和58次气脑造影。
