摘要
超声造影(CEUS)是可用于在体评估微血管灌注并量化微血管血容量的成像技术,现已发展成为高度专业化的医学诊断领域,其独特之处在于可实时显示造影剂在组织中的灌注与廓清过程,显示并量化病灶微血管灌注特征,提高诊断敏感性和特异性。近年CEUS相关临床应用指南也在不断推出及更新。除灌注成像外,未来CEUS还将用于临床分子成像,并实现携带药物的精准治疗。
Contrast-enhanced ultrasound(CEUS)is an imaging technique that can be used to in vivo assess microvascular perfusion and quantify microvascular blood volume,which has developed into a highly specialized area of medical diagnostics.The unique feature of CEUS is real-time representation of the inflow and outflow behavior of the contrast medium in the tissue,accordingly allowing the characterization of microvascular perfusion to be visualized and quantified and increasing the sensitivity and specificity in assessment of lesions.Over the years,universal guidelines regarding the application of CEUS in clinical settings had been developed.In addition to perfusion imaging,CEUS will be applied in clinical practice for molecular imaging and as therapeutic agent to realize site-specific drug delivery.
