实时三维超声心动图在心脏占位性病变中的应用价值

目的:探讨实时三维超声心动图(RT3DE)在心脏占位性病变中的临床应用价值。方法:28例心脏占位性病变患者接受了二维超声心动图(2DE)和RT3DE检查,均经手术及病理证实。根据图像质量将RT3DE图像分为I、II和III级。结果:RT3DE图像质量I级者达93%(26/28),II级者占7%(2/28),无III级图像者。RT3DE可更直观地显示心脏占位性病变部位、形态及其与邻近结构的关系。结论:与2DE相比, RT3DE可对心脏占位性病变提供更丰富的形态学信息,有助于其治疗措施的选择。

Application of real-time three-dimensional echocardiography in cardiac space-occupying lesions

Objective:To evaluate the value of real-time three-dimensional echocardiography(RT3DE) in cardiac space-occupying lesions. Methods:Twenty-eight patients with cardiac space-occupying lesions, determined by surgical operation and pathology, undertook two-dimensional echocardiography(2DE) and RT3DE. The three-dimensional images were divided into grade I, II and III according to the imaging qualities. Results:The three-dimensional images were assess as grade I in 93%(26/28), grade II in 7%(2/28) and no grade III images. The location, morphology and relation with neighboring structures of cardiac space-occupying lesions could be displayed more intuitively by RT3DE. Conclusion:Compared with 2DE, RT3DE may provide more abundant morphologic information of cardiac space-occupying lesions and is of great benefit to its treatment planning.
