Abstract

Abstract: Ultrasound Doppler method of Superb Microvascular Imaging (SMI) can significantly visualize low-velocity blood flow using a unique algorithm. We scanned placenta antenatally using SMI and compared those findings with histological findings after delivery in cases with placental abnormalities. In normal, SMI expresses stem villous vessels connecting to the tertiary villous vessels which are sharply diminished, and expresses intervillous blood flow as "scatter." Placental infarction was expressed as an anechoic area in SMI. Avascular villi was expressed as absent villous blood trees in a background scatter flow in SMI. In this report, we demonstrated typical SMI findings of the pathologic placenta as a pilot study.
