【摘要】 目的　评价三维超声在显示正常血管结构及诊断血管疾病方面的应用价值。方法　对 17例正常人、2 2例血管疾病患者的血管进行三维超声检查。结果　所有三维成像均在扫查后 10～ 3 0s内完成 ;在正常人中 ,可清晰显示正常血管的立体关系 ,可观察到肝、肾等实体性脏器内正常血管的立体构筑 ;通过自由旋转的画面 ,在一幅图像中可以同时观察到颈总动脉、颈外动脉及颈内动脉以及它们的立体位置关系 ;在肝移植患者中可以准确地显示移植肝内门静脉及肝静脉血管的连续性。在有血管疾病的患者中 ,同样可以立体地显示出病变的部位和程度 ,更直观地观察到血管的狭窄、瘤状扩张及弯曲蛇行等病变。结论　三维超声可以迅速准确地显示正常血管的立体结构及血管疾病的病变部位和程度 ,提供了二维超声图像所缺少的立体空间位置关系的信息。三维超声有助于对血管疾病的诊断 ,在临床上具有较高的应用价值。更多还原

【Abstract】 Objective To assess the clinical value of three-dimensional ultrasonography (3DUS) in normal vascular structures and vascular diseases. Methods Thirty-nine 3DUS images were reconstructed,including 17 normal vascular structures and 22 vascular diseases. 3DUS reconstruction was introduced by the maximum intensity projection (MIP) method. A series of 3DUS image was performed using GE Logiq 500 and Logiq 700. Results In all cases, 3DUS images were constructed within 10-30 seconds after free hand scanning. Internal, external and common carotid arteries were also showed in the same rotating 3DUS display simultaneously. The continuity of the transplanted hepatic portal vein were demonstrated clearly in rotating mode 3DUS display and consistent with angiography or computer tomography findings. In cases of various vascular diseases, the degree and location of stenosis or aneurysm of the vessels could be stereoscopically visualized, easy to understand especially for a surgeon who evaluates a preoperative state. Conclusions The 3DUS can display normal or abnormal vascular anatomy clearly. 3DUS image could supply more information than original two-dimensional image, and is useful in the diagnosis of various vascular diseases.更多还原
