Introduction
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.
The ultrasound technique can be used at any stage during pregnancy for embryo and placenta monitoring. Normal developmental ultrasound and features are listed on a separate page (More? Ultrasound) all content is for educational use only.
Some first trimester (GA 11-14 weeks) diagnostic measurements can include:
- Trisomies - Nuchal translucency (NT), nasal bone length (NBL), prenasal thickness (PT)
- Cardiovascular - tricuspid valve regurgitation (TR), "a"-wave pattern, DV PIV, S-wave (peak systolic velocity), D-wave (peak diastolic velocity), a-wave (atrial contraction in late diastole), time-averaged maximum velocity (TAMXV)
The ultrasound movies can be viewed in two ways:
