CT is presented as an alternative to barium enema examination for the investigation of the colon in frail elderly patients. Carcinomas can be detected reliably and the investigation is better accepted by patients and staff alike. Furthermore, extracolonic lesions are shown. Obviously small polyps are missed, but such lesions are less relevant in older patients. The CT technique is described, and some of the initial difficulties encountered during the adoption of this policy are discussed.
对于体弱的老年患者，CT被视为替代钡灌肠检查用于结肠检查的一种方法。可以可靠地检测出癌症，并且患者和医护人员都更容易接受这种检查。此外，还能显示结肠外病变。显然，小息肉会被漏诊，但这类病变在老年患者中相关性较小。本文描述了CT技术，并讨论了在采用该方法过程中最初遇到的一些困难。
