The use of intrarectally administered plain tap water as a contrast medium for CT scan of the rectum and sigmoid combined with iv iodine contrast medium was prospectively studied in 28 patients. This method allowed correct demonstration of mural wall abnormalities in all patients and therefore represents a simple, inexpensive, and efficient modality for CT study of the rectum and sigmoid.
对28例患者进行了前瞻性研究，采用经直肠注入普通自来水作为直肠和乙状结肠CT扫描的对比剂，并联合静脉注射碘对比剂。该方法能正确显示所有患者的肠壁异常，因此是一种用于直肠和乙状结肠CT检查的简单、廉价且有效的方法。
