OBJECTIVE
With major efforts being made to reduce radiation exposure in CT, one area of practice that requires additional improvement is limiting the number of acquisitions for body CT imaging. This review article defines best MDCT practice in terms of tailored abdominal CT protocols, designed to maximize lesion detection while limiting radiation exposure.
CONCLUSIONS
The literature defines optimal acquisitions for a range of abdominal CT indications, with precontrast and delayed acquisitions being least commonly indicated.
目的
在大力致力于减少CT辐射暴露的过程中，需要进一步改进的一个实践领域是限制体部CT成像的采集次数。这篇综述文章根据量身定制的腹部CT方案定义了最佳的多层螺旋CT（MDCT）实践，旨在在限制辐射暴露的同时最大化病变检测。
结论
文献确定了一系列腹部CT适应证的最佳采集方式，其中平扫和延迟采集最不常用。
