Superb micro-vascular imaging (SMI) Doppler has proven to be a valid method to assess normal placental micro-vascularization. In this study, we present the application of SMI Doppler to assess placental micro-vascularization in cases of placental insufficiency. We observed fewer secondary and tertiary villi in cases of intra-uterine growth restriction, as well as a lower pulsatile index of secondary villi. The observations made in our study stress the diagnostic potential of SMI Doppler in placental insufficiency.
卓越的微血管成像（SMI）多普勒已被证明是评估正常胎盘微血管形成的有效方法。在本研究中，我们介绍了 SMI 多普勒在评估胎盘功能不全时胎盘微血管化的应用。我们观察到宫内生长受限的病例中二级和三级绒毛较少，以及二级绒毛的搏动指数较低。我们的研究结果强调了 SMI 多普勒在胎盘功能不全中的诊断潜力。
