ABSTRACT
Color Plate E Absence of diastolic flow (resistance index 1.0) in the umbilical artery observed in a fetus with intrauterine growth restiction and trisomy 21
Color Plate F Power Doppler image of a sacrococcygeal teratoma detected at 23 weeks of pregnancy
Color Plate G The same case as in Plate F. Pulsed Doppler assessment of the intratumoral vessels reveals low resistance to blood flow (resistance index 0.19)
Color Plate H Three-dimensional power Doppler angiography demonstrates rich vascularization and spatial distribution of the vessels within the sacrococcygeal teratoma
Color Plate I Transvaginal three-dimensional power Doppler scan of a polycystic ovary. Note the peripheral distribution of small follicles and increased vascularity within the ovarian stroma
Color Plate J Multiplanar image of the uterus after injection of echogenic contrast medium as obtained by power Doppler ultrasound. This modality facilitates visualization of the normal uterine cavity in three orthogonal projections; the triangular shape of the uterine cavity is best imaged in the frontal section
Color Plate K Three-dimensional power Doppler image of the entire tubal length and spillage of the contrast medium through the fimbrial end as demonstrated by echoenhanced hysterosalpingography
Color Plate L Three-dimensional power Doppler hysterosonosalpingography. Note the normal triangular uterine cavity with passage of the contrast through the right Fallopian tube
