Superb microvascular imaging (SMI) reduces motion artifacts significantly and allows visualization of low-velocity blood flow in vessels; thus, thrombi are clearly demonstrated compared to conventional B-mode and color Doppler imaging. Ultrasonographic images of the lower extremities of a 69-year-old woman with acute ischemic stroke complicated with deep vein thrombosis (DVT) are presented. Because SMI allows visualization of low-velocity blood flow, echo contrast between the thrombus and the surrounding flow makes it possible to clearly visualize the thrombus. SMI is a useful method to evaluate DVT, especially early after thrombus formation when it is difficult to delineate size and length because of echolucency.
超微血管成像（SMI）显著减少运动伪影，并能显示血管内的低速血流；因此，与传统B模式和彩色多普勒成像相比，血栓能更清晰地显示。本文展示了一名69岁急性缺血性中风合并深静脉血栓形成（DVT）女性患者下肢的超声图像。由于SMI能显示低速血流，血栓与周围血流之间的回声对比使得清晰显示血栓成为可能。SMI是评估DVT的一种有用方法，尤其是在血栓形成早期，由于回声透亮而难以描绘血栓大小和长度的时候。
