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 method and clinical value of using real-time three-dimensional echocardiography to detect, cut and display the cardiovascular structure of normal adults. Methods In 12 normal adults, static and dynamic observation of the anatomical structures of the heart and large blood vessels was conducted by using three techniques: two-dimensional ultrasound, real-time three-dimensional ultrasound and full volume three-dimensional ultrasound. The anatomical information is compared and analyzed. Results In all patients, satisfactory two-dimensional ultrasound, real-time three-dimensional and full-capacity three-dimensional images were obtained. Compared with the traditional two-dimensional ultrasound technique, real-time three-dimensional ultrasound technology has the function of immediately displaying any structure in the cardiac “cake piece” Full three-dimensional ultrasound technology has the advantage of rapidly displaying the three-way orthogonal cross-section and spatial adjacency relationship of any structure in the entire “pyramid” image of the heart. Conclusion The real-time three-dimensional and full-capacity three-dimensional ultrasound technology can display the traditional two-dimensional ultrasound technology can not display the structure, thereby reducing the subjectivity and blindness of two-dimensional ultrasound and improve the diagnostic accuracy and efficiency of echocardiography, has important clinical value.
