1035: 3D/4D Ultrasound Examinations in the First Trimester of Pregnancy with Minimal Exposition Time

Abstract

Ultrasound examinations in first trimester of pregnancy with minimal exposition time. 534 pregnant women with intrauterine pregnancies were examined by 3D/4D ultrasound equipment. Dates of gestation varied from 5 to 13 weeks. The examination included several 3D/4D scans with a summery exposition time of no more than 20 seconds followed by a virtual examination via special software (Medison 3DXI). As a result, abnormal pregnancies were detected in 22 cases (intrauterine hematoma, the absence of heartbeat, anembryonia, increased nuhal translucency space, anomalies of embryo and fetus). In 512 cases normal pregnancies were revealed. All parts of gestational sacs and fetuses anatomy were clearly visible in all cases. In 2 cases of 17 multiple pregnancies a mistake was made. The results of these examinations were verified by dynamic ultrasound exams during following weeks of gestation. The use of 3D/4D ultrasound virtual scan in first trimester gave us satisfactory results with a very limited exposition of scanning. This examination type can be called “ecological ultrasound” as it greatly reduces the possibility of unfavourable ultrasound influence on the fetuses.
