Color-coded circulation is a display method that generates dynamic color-coded images based on the time of arrival of contrast agents using parametric imaging to create video displays. By cyclically displaying information in color according to the arrival time of the contrast agent at each pixel, anatomical blood vessel paths and blood flow information can be simultaneously visualized. Three-dimensional (3D) helical stents increase wall shear stress due to swirling flow and prevent intimal hyperplasia. To the best of our knowledge, there are no reports on the visualization of this swirling flow using color-coded circulation. Here, we report the use of color-coded circulation to visualize the swirling flow following the placement of a 3D helical stent in the left superficial femoral artery. Color-coded circulation may facilitate the evaluation of contrast agent distribution and blood flow, which may otherwise go undetected with digital subtraction angiography.
彩色编码循环是一种显示方法，它基于造影剂的到达时间，使用参数成像生成动态彩色编码图像以创建视频显示。通过根据造影剂在每个像素处的到达时间循环地以颜色显示信息，可以同时可视化解剖学血管路径和血流信息。三维（3D）螺旋支架由于涡流会增加壁面剪应力并防止内膜增生。据我们所知，尚无关于使用彩色编码循环可视化这种涡流的报道。在此，我们报告使用彩色编码循环来可视化在左股浅动脉放置3D螺旋支架后的涡流。彩色编码循环可能有助于评估造影剂分布和血流，否则这些情况可能在数字减影血管造影中无法检测到。
