The place of four-dimensional ultrasound in evaluating fetal anomalies

摘要: To analyze the capability of four-dimensional surface rendering mode ultrasound (4D SRM USG) in detection fetal abnormalities, and also compare it with 2D USG. A total 1,379 pregnant women were enrolled study, they all underwent USG screening. In same session, subsequently screened using 4D The findings both methods compared. 194 anomalies detected 176 by When cases, including superficial non-superficial anomalies, evaluated together, we found that was significantly better than detecting (p < 0.001). However, superior to terms image quality, clarity, distinction between surrounding structures, intelligibility among cases a anomaly (p < 0.005). is malformations related fetus face, spine, extremities, abdominal wall, body surface. only approximately half showed quality 15 % cases. Therefore, may be suitable for use as complementary tool evaluation especially those extremity, wall.
