摘　　要：目的　探讨应用实时三维超声心动图新技术探测、切割和显示正常成人心血管结构的方法学及临床价值。方法　在 1 2例正常成人中 ,应用二维超声、实时三维超声和全容量三维超声等 3种技术对心脏和大血管的解剖结构进行多个方位和切面观的静态和动态观察 ,对所获得的解剖信息进行比较和分析。结果　在所有患者中获得了满意的二维超声、实时三维和全容量三维的图像 ,与传统的二维超声技术相比 ,实时三维超声技术具有即刻显示心脏局部“蛋糕块”图像内任一结构的三向正交切面和空间毗邻关系的优点 ,全容量三维超声技术具有迅速显示心脏整体“金字塔”图像内任一结构的三向正交切面和空间毗邻关系的优点。结论　实时三维和全容量三维超声技术可显示传统二维超声技术无法显示的结构 ,从而减少二维超声检查的主观性和盲目性 ,提高超声心动图的诊断准确率和工作效率 ,具有重要的临床价值。Objective To explore the methodology of sca nning, cutting and measuring normal cardiovascular structures by real-time three-dimensional echocardiography (RT-3DE) and it's clinical applications. Methods Conventional two-dimensional echocardiography (2-DE), RT-3DE and full volume three-dimensional echocardiography (FV-3DE)were performed in 20 normal volunteers to visualize normal cardiovascular structures in multiple orientations and cross sections both in static and dynamic fashions, and all echo images derived by three techniques were compared and analyzed.Results Technically satisfactory 2-DE, RT-3DE and FV-3DE images were obtained in all subjects. Compared with conventional 2-DE technique, RT-3DE has the advantages of instantly displaying three orthogonal planes and spatial relationships of any cardiac structure within a 'piece of cake' images of a regional heart, while FV-3DE has the superiority in rapidly depicting three orthogonal planes and spatial relationships of any cardiac structure within a pyramid images of a whole heart. Conclusions Both RT-3DE and FV-3DE techniques can display cardiac structures unobtainable by 2-DE and are useful in reducing the subjectivity and blindness of 2-DE studies, which may enhance the diagnostic accuracy and work efficiency of echo laboratories and produce important clinical values.
