Ultrasound - Abnormal
This page links to movies of abnormalities of human development as detected by ultrasound. Ultrasound movies or images are now commonly seen by parents in the first trimester as a clinical non-invasive early method of embryo staging (ageing) and early detection of abnormalities. Later in the second and third trimester ultrasound is used as a method for checking fetal growth and detection of developmental abnormalities. Ultrasound can also be used with other techniques to locate both embryo and placenta for other prenatal tests.
