Patient's question:
What is fibrocystic breast changes? First question supplement: I am six months pregnant. Do I need to do a color ultrasound? Can I do a regular black and white ultrasound?Doctor's answer:
The best time for a four-dimensional color Doppler ultrasound examination for a single fetus is at 24-27 weeks of pregnancy. The best time for a twin pregnancy is between 20-22 weeks. This period is ideal because the fetuses are of moderate size, with sufficient amniotic fluid, making it easier to obtain relatively clear images.The content of a four-dimensional color Doppler ultrasound examination includes:
1. Facial abnormalities of the fetus, such as cleft lip and palate.
2. Nervous system: anencephaly, hydrocephalus, microcephaly, spina bifida, and meningocele.
3. Digestive system: omphalocele, evisceration, intestinal atresia, and Hirschsprung's disease.
4. Urinary system: hydronephrosis, polycystic kidney disease, megacystia, and urethral obstruction.
5. Other abnormalities: limb malformations, conjoined twins, congenital heart disease, and teratogenesis.
