摘要
目的观察超声血管增强技术在诊断胎儿隔离肺中的临床应用价值。方法应用超声血管增强技术对11例胎儿隔离肺患者进行检查,显示病灶区血管,并与传统二维彩色多普勒速度图和能量图相比较。结果11组图像中,CDV、CDE和VET图像均可不同程度地显示病灶处的异常血管,但所提供的信息有一定差异。CDV和CDE可显示较大血管走行和分布,而VET可清晰辨别血管腔,显示细小分支;CDV能分辨血流方向,对判断血管的性质有较大意义。VET图像满意度优于CDV和CDE,差异有统计学意义(P<0.05);CDV和CDE图像满意度评分差异无统计学意义(P>0.05)。结论超声血管增强技术能提高血管与周边组织对比分辨力,在血管管腔及细小分支的显示方面有独特的优势,对诊断胎儿隔离肺有一定应用价值。
Objective To assess the clinical value of vascular enhancement technology（VET） in diagnosis of fetal pulmonary sequestration（PS）.Methods Color Doppler velocity（CDV）,color Doppler energy（CDE） and VET were performed in 11 fetus with PS to display the vessels in region of interest.Results The abnormal vessels in region of interest were displayed in distinct degree with CDV,CDE and VET.The courser and disposition of the great vessels were displayed with CDV and CDE,while lumen of blood vessel was clearly discriminated with VET,while CDV depicted the direction of blood flow.Satisfaction assessment of the VET image was superior than those of CDV and CDE image（P〈0.05）.No difference was found between the satisfaction assessment of the CDV and CDE images（P〉0.05）.Conclusion VET can improve the contrast resolution,having superiority in displaying vessels and fine branches,therefore has clinical value in the diagnosis of fetal PS.
