Abstract：
Using color Doppler flow imaging or high-definition flow imaging with three-dimensional volume or spatio-temporal image correlation (STIC) in the glass-body mode allows displaying both gray-scale and color information of the heart cycle-related flow events and vessel spatial relationship. Conventionally, STIC in the glass-body mode has been used to examine the fetal heart and assess heart defects. Recently, a novel application of STIC in the visualization of abdominal precordial veins and intraplacental vascularization in singleton pregnancies has been reported. The aim of this present review is to discuss the use of color Doppler with three- and four-dimensional ultrasonography in the evaluation of extracardiac, placental, umbilical cord and twin abnormalities with examples. The glass-body mode is complementary to conventional 2D ultrasonography. Further studies are required to investigate use of the glass-body mode in the assessment of intraplacental vascularization in singleton and twin pregnancies.
摘要：
在玻璃体模式中使用彩色多普勒血流成像或具有三维体积或时空图像相关性(STIC)的高清晰度血流成像允许显示与心脏周期相关的血流事件和血管空间关系的灰度和颜色信息。传统上,玻璃身体模式的STIC已用于检查胎儿心脏并评估心脏缺陷。最近,已经报道了STIC在单胎妊娠中的腹部心前静脉和胎盘内血管形成可视化中的新应用。本文的目的是讨论彩色多普勒与三维和四维超声检查在心外评估中的应用。胎盘,脐带和双胞胎异常的例子。玻璃体模式是常规2D超声检查的补充。需要进一步的研究来研究玻璃体模式在评估单胎和双胎妊娠胎盘内血管形成中的用途。
