摘要
目的：评价口服水剂、水灌肠及两者联合应用充盈肠道后,使用MSCT显示成人正常肠道的能力。材料和方法：将43名非肠道病变志愿者分别采用口服水剂法(21例)、水灌肠法(12例)、双重法(口服水剂和水灌肠联合应用,10例)充盈肠道,然后行MSCT平扫和增强扫描并进行图像重建,对小肠和大肠各肠段充盈状态进行评价。结果：口服水剂法回肠充盈良好,水灌肠法大肠充盈良好,双重法回肠及大肠均充盈良好。口服水剂法小肠充盈优于水灌肠法,与双重法无显著差异,大肠充盈状态水灌肠法明显优于口服水剂法,与双重法无显著差异。结论：口服水剂和水灌肠联合应用可以在MSCT同时较好地充盈显示小肠和大肠,而两种方法单独使用则仅能分别充盈显示小肠和大肠,需要根据显示目的选择相应的充盈方法。
Purpose： To evaluate capability of MSCT in displaying normal bowels after that they were distended by oral water, water enema and their combination. Materials and Methods： 43 volunteers without gastrointestinal lesions or severe systematic disorders were divided into 3 groups. 21 cases with oral water, 12 cases with water enema and 10 cases with their combination. Pre- and post-contrast MSCT scans were performed and the images were reformatted and evaluated to display the filling effect of bowels including small bowels and colons. Resuits： The ileums were well distended and displayed in oral water group, the colons were well distended in water enema group and both of them were well distended in the combination group. The ileums were delineated better in oral water group than in water enema group （ where P〈0.05）, and the oral water group had the same effect as the combination group （where P〉0.05）. The colons were delineated better in water enema group than in oral water group （where P 〈0.05）, and the water enema group had the same effect as in the combination group （where P 〉0.05）. Conclusion： Combination application of oral water and water enema can delineate the small bowels and colons well on MSCT, while each of them can only delineate the small bowels or colons depending on the study purpose.
