Ultrasound color doppler
Three-dimensional and four-dimensional ultrasound of the embryo is the most recent type of ultrasound device. The sono is performed by the "Coler-Dalper" method (three-dimensional and four-dimensional fetal) in an ultrasound unit. An intravenous package is applied. Ultrasound includes deep and superficial routine ultrasounds, transvaginal, colder dulprer and three-dimensional and four-dimensional embryos with CD preparation.
