The effect of computerized cranial tomography (CCT) on physicians' diagnostic and therapeutic plans in 194 patients scanned consecutively during a 17-day period at the Massachusetts General Hospital was studied. Use of CCT substantially decreased the perceived need for other neurodiagnostic tests in this patient population. There was a reduction of a least 41% in radionuclide scans, 52% angiograms, and 73% in pneumoencephalograms compared to the needs projected had CCT not been available. Therapy was altered after 37 scans in 36 patients (19% of those examined): new treatment was begun after 15 scans, previously planned therapy became more precise after 9 scans, treatment was found to be unnecessary after 7 scans, and treatment was abandoned as worthless after 6 scans.
在马萨诸塞州综合医院为期17天的时间里，对194例连续接受计算机断层扫描（CCT）的患者进行了研究，以探讨CCT对医生诊断和治疗方案的影响。在这一患者群体中，CCT的使用显著降低了对其他神经诊断检查的需求。与未使用CCT时预计的需求相比，放射性核素扫描减少了至少41%，血管造影减少了52%，气脑造影减少了73%。36例患者（占检查患者的19%）在进行了37次扫描后治疗方案发生了改变：15次扫描后开始了新的治疗，9次扫描后之前计划的治疗变得更加精确，7次扫描后发现治疗不必要，6次扫描后因治疗无效而放弃治疗。
