Ultrasound - Abnormal

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?
