中文摘要:
      目的 评价实时双平面成像(Bi-Plane)技术在测量不同孕周正常胎儿二尖瓣环面积中的可行性。方法 利用常规二维超声和实时Bi-Plane技术观察159胎二尖瓣形态结构,测量二尖瓣环面积,分析测值与孕周的相关性,记录成像率和采集时间,并进行统计学分析。结果 常规二维超声和实时Bi-Plane技术所测二尖瓣环面积与孕周均呈正相关(r=0.71、0.75,P均<0.05)。2种方法测量二尖瓣环面积的成像率(χ2=4.375,P=0.036)和采集时间(t=6.11,P<0.05)差异均有统计学意义。结论 实时Bi-Plane技术测量二尖瓣环面积直接、准确、方便、快捷,可以评估胎儿二尖瓣的异常改变,为临床提供重要的诊断依据。
英文摘要:
      Objective To assess the feasibility of real-time Bi-Plane in observing normal mitral annular areas in different gestational ages. Methods Routine two-dimensional echocardiography and real-time Bi-Plane were used to observe mitral structure and measure the mitral annular area in 159 fetuses. Pearson correlation analysis was used to evaluate the correlation of the areas with gestational age. Visualization rates and acquisition time were recorded and analyzed statistically. Results The mitral annular areas measured by two techniques were both correlated to the gestational age (r=0.71, 0.75, both P<0.05). There were significant differences in visualization rate (χ2=4.375, P=0.036) of mitral annular area and acquisition time (t=6.11, P<0.05) between routine two-dimensional echocardiography and real-time Bi-Plane. Conclusion Real-time Bi-Plane technique is direct, accurate, convenient and fast in observing mitral prenatally. By using Bi-Plane technique to measure mitral annular area, abnormal morphology changes of mitral valve can be evaluated, so as to provide great application value for clinic.
