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.

The ultrasound movies can be viewed in two ways:

Clicking either the movie image or "Page" text below the image opens a new page with both the movie and a more detailed text description of features. Embedded movies then play by clicking the play triangle icon lying over the movie image.
Clicking on the "Play" link will open the MP4 movie version alone on a new page.

Please note that original Quicktime and Flash movie versions will now forward to the MP4 movie page. Also tt the bottom of this current page is further ultrasound information and links to internet ultrasound sites. Abnormal developmental ultrasound and features are listed on a separate page (More? abnormal ultrasound) all content is for educational use only.
