In this review, we attempt to address many of the issues that are related to ensuring patient benefit in body CT, balancing the use of ionizing radiation and iodinated contrast media. We attempt to not only summarize the literature but also make recommendations relevant to CT protocols, including the technical parameters of both the scanner and the associated contrast media.
Although CT is a powerful tool that has transformed the practice of medicine, the benefits are accompanied by important risks. Radiologists must understand these risks and the strategies available to minimize them as well as the risks associated with contrast medium delivery in abdominal CT.
在本次综述中，我们试图解决许多与确保 CT 检查中患者获益相关的问题，以平衡电离辐射和碘造影剂的使用。我们不仅试图总结文献，还对 CT 方案提出相关建议，包括扫描仪和相关造影剂的技术参数。
虽然 CT 是改变医学实践的强大工具，但益处伴随着重要风险。放射科医生必须了解这些风险以及可用于最大程度降低这些风险的策略，还必须了解与腹部 CT 造影剂给药相关的风险。
