Bowel preparation represents an essential part of CT colonography, as the accuracy of the exam is strongly related to the adequacy of colonic cleansing, and a poor bowel preparation may compromise the diagnostic quality even despite optimization of all other acquisition parameters. Residual stool and fluid in the large bowel may affect the interpretation of the exam and may increase the number of false positives and false negatives. In this regard, the majority of patients having undergone CT colonography state that bowel preparation is the most unpleasant part. Unfortunately, to date no definite consensus has been reached about the ideal bowel preparation technique, and there is great variability in preparation strategies across diagnostic centers. The purpose of this review article is to describe the development and evolution of bowel preparation techniques in order to choose the best approach for optimizing the diagnostic quality of CT colonography in each patient.
肠道准备是 CT 结肠成像的重要组成部分，因为检查的准确性与结肠清洁度密切相关，如果肠道准备不佳，即使优化了所有其他采集参数，也可能会影响诊断质量。大肠中残留的粪便和液体可能会影响检查的解读，并可能增加假阳性和假阴性的数量。在这方面，大多数接受 CT 结肠成像检查的患者表示，肠道准备是最不愉快的部分。不幸的是，迄今为止，对于理想的肠道准备技术尚未达成明确共识，不同诊断中心的准备策略存在很大差异。本文的目的是描述肠道准备技术的发展和演变，以便为每位患者选择最佳方法来优化 CT 结肠成像的诊断质量。
