VCI-C平面及三维超声重建对股动脉粥样硬化斑块的诊断价值

Diagnosis of atherosclerotic plaque in femoral artery with volume contrast imaging C-plane and 3D ultrasonic reconstruction

目的:探讨容积对比成像(volumecontrastimaging CPlane,VCI C)平面及三维超声(3D)重建评价股动脉粥样硬 化斑块不同形状的临床应用价值及可行性.方法:对15例股 动脉粥样硬化斑块进行二维超声(2D)、VCI C平面与3D重 建检查,并对相关图像进行分析.结果:15例斑块中,右侧9 例(60%),左侧6例(30%),左、右腿同时合并斑块12例 (80%);强回声斑块7例(46.7%),低回声斑块5例 (33.3%),混合回声斑块3例(20%),VCI C平面能显示与 2D声束相垂直平面的声像图特征,能从另一视角观察斑块的 特征;3D对股动脉粥样斑块重建后的图像空间立体感强. 结论:VCI C平面超声成像结合3D重建信息量大,可以进行 任意角度的图像后处理,在显示股动脉粥样硬化斑块中能比 2D提供更多的诊断信息.

AIM: To explore the value of volume contrast imaging C plane (VCI-C) and 3D ultrasonic (3D US) reconstruction in the diagnosis of atherosclerotic plaque in femoral artery. METHODS: Fifteen cases of atherosclerotic plaque (AP) in femoral artery were diagnosed and analyzed with traditional 2D ultrasound (2D US), VCI-C plane and 3D US reconstruction. RESULTS: There were different advantages and disadvantages of traditional 2D ultrasound, VCI-C plane and 3D US reconstruction in the diagnosis of atherosclerotic plaque in femoral artery. The disadvantages of traditional 2D US were that its stereoscopy was worse. VCI-C plane could produce images which were vertical to transmitted ultrasound. The advantages of 3D US reconstruction were that it had good space visualization, but it was apt to be influenced by many factors. CONCLUSION: In the diagnosis of atherosclerotic plaque in femoral artery, VCI-C plane and 3D US reconstruction can provide more useful information than those of traditional 2D US.
