双能量CT在体外冲击波碎石术前测定结石成分中的应用进展
|
摘要
双能量CT已被证明在泌尿系结石成分诊断中起着非常重要的作用,且在制定患者的治疗方案上它能起到更好、更准确的指导作用。本文首先介绍了双能量CT的原理和优势,然后分析了ESWL碎石效果与结石硬度、结石成分的关系,通过综合国内外的最新研究进展,综述了双能量CT预测结石成分的原理及研究现状,并对双能量CT成像对泌尿系结石的未来研究方向做出展望。
Dual-energy CT has been proved to play a very important role in the diagnosis of urinary stone components, and it can play a better and more accurate guiding role in the development of patients' treatment program. In this paper, the principle and advantages of dual-energy CT were introduced, and then the relationship between ESWL lithotripsy effect and stone hardness and stone composition was analyzed. By summarizing the latest research progress at home and abroad, the principle and research status of dual-energy CT in predicting the components of urinary calculi were summarized, and the future research direction of dual-energy CT imaging in urinary calculi was prospected.
