Figure 2: Ultrasound findings using superb microvascular imaging
of abnormal placental pathology
- Infarction: Neither the background ”scatter” and “villous
tree” were detected, resulting in an echoic space (triangle).
- Avascular terminal villi: Only the background ”scatter” is
observed without normal villous trees.
- Dilatation of stem villi (Congestion): The stem villi were
clearly dilated compared with the surrounding villous stem vessels.
- Hyper-vascular terminal villi (Chorangiosis): Terminal villi
are highly echoic compared with standard villi and appear to be
”fluffy” (triangle).
