The impact of cranial computed tomography (CCT) on the cost effectiveness of a neurodiagnostic work-up was evaluated. With the use of CCT, 170 air studies and 171 angiographic procedures were made unnecessary in the 444 patients reviewed. Admission was not necessary in 58% of the outpatients examined and the hospital stay was shortened significantly for inpatients. Even considering the cost of the examination and the few extra investigations generated, a single CCT unit can effect savings of up to $2,000,000 per year.
评估了头颅计算机断层扫描（CCT）对神经诊断检查成本效益的影响。在444例接受检查的患者中，使用CCT后，170次空气造影检查和171次血管造影检查不再必要。58%接受检查的门诊患者无需住院，住院患者的住院时间显著缩短。即使考虑到检查成本和由此产生的少量额外检查，一台CCT设备每年最多可节省200万美元。
