摘要 造影增强超声技术是指在静脉弹丸式推注超声造影剂后,利用人体组织明显不同的回声特性和显著的声阻抗差异,将病灶从周围组织凸显出来的成像技术.造影增强超声内镜(contrast-enhanced endoscopic ultrasonography,CE-EUS)即是将其发展到了超声内镜领域.CE-EUS能以最接近病灶的方式显影成像,减少腹壁组织和空气干扰,在一些疾病诊断中,比经腹超声、CT、MRI等检查手段的准确率还高[1-2].此外,它具有无辐射、无创性、操作简便、适用面广等优点.因此,CE-EUS的临床应用越来越受到人们的关注.现就超声造影剂、图像分析软件、适应证等方面,阐述CE-EUS的研究进展.
