Abstract
In this prospective cohort study, we examined the utility of elastography to evaluate the fetus and placenta. Pregnant women in their third trimester of pregnancy, by which time the placenta has formed, were included in this study. A total of 111 women underwent ultrasound examinations, including elastography. Elastographic evaluation was performed using two protocols. First, the placental index (PI) was measured, which quantitatively assesses the hardness of tissue. Second, regions of interest (ROI) were categorized into 3-step scores according to the frequency of the blue area (hardness of placental tissue score [HT score]), which is a qualitative method. After delivery, 40 of the 111 placentas were pathologically examined. The average PI was 44.3 (± 29.4) in the in utero SGA group, which was significantly higher than that in the normal group (8.8 (± 10.0); p < 0.01) during pregnancy. There was a significant correlation between the PI and z score for estimated fetal weight (EFW) (r = -0.55; p < 0.01). Moreover, a significant positive correlation was observed between the PI and the z score of birth weight (r = -0.39; p < 0.01). Pathological ischemia findings of the placenta were identified in 67% of the HT score 3 group, repre...Continue Reading
