An approach to evaluating the cost-effectiveness of high-technology diagnostic equipment has been devised, using the introduction of computerised axial tomography (CAT) as a model. With the advent of CAT scanning, angiography and air encephalography have a reduced, though important, role in investigating intracranial disease, and the efficient use of conventional equipment requires the centralisation of neuroradiological services, which would result in major cash savings. In contrast, the pattern of demand for CAT scanning, in addition to the acknowledged clinical efficiency of the scanner and its unique role in the head-injured patient, ephasies the need for improved access to scanners. In the interest of the patients the pattern of service must change.
一种评估高科技诊断设备成本效益的方法已经设计出来，以计算机断层扫描（CAT）的引入为模型。随着CAT扫描的出现，血管造影和气脑造影在颅内疾病检查中的作用虽然重要但有所减少，而有效使用传统设备需要神经放射学服务的集中化，这将带来大量现金节省。相比之下，CAT扫描的需求模式，除了扫描仪公认的临床效率及其在头部受伤患者中的独特作用外，强调了改善扫描仪可及性的必要性。为了患者的利益，服务模式必须改变。
