A microcomputer was used to analyse prospectively 1,000 sequential computed tomographic (CT) brain scans to assess whether the scanner was being used in a cost-effective and efficient manner. Of the patients scanned 58% had cerebral lesions. All the usual indications for CT examination were shown to be worth while, the exception being psychiatric cases.
一台微型计算机被用于前瞻性分析1000例连续的脑部计算机断层扫描（CT），以评估该扫描仪的使用是否具有成本效益且高效。在接受扫描的患者中，58%有脑部病变。CT检查的所有常见指征都被证明是有价值的，精神科病例除外。
