The most common form of ectopic pregnancies are those that occur with premature implantation in the uterine or fallopian tubes. The movie above shows an ectopic embryo (less than 10 weeks gestation) which has implanted in the left uterine tube. (More? Week 2 - Abnormal Development)
Normal Right Tube - The movie starts by showing the normal right uterine tube (RT).
Ectopic Left Tube - The scan then moves to the left uterine tube (LT) where ectopic implantation has occurred. Also visible is the left ovary (L OV) and the uterus (UT).
Zoom Region - A region of the whole ultrasound can be zoomed in for more detail.
Heart - In the movie, the zoomed image shows the embryo has developed to the stage where a beating heart can be detected by ultrasound.
Limbs - Also visible are the developing upper and lower limbs.

This ultrasound scan movie shows how an ectopic pregnancy can be detected or confirmed by this technique.
Special thanks to Dr Andrew McLennan, Foetal Medicine Unit, Royal North Shore Hospital for original video materials.
Normal development features are listed on a separate page Normal Ultrasound.
There also an about movies page which has technical details and terms listed.
Both Mac and PC computers require the Quicktime plug-in to be present in your browser or on your computer.
Internet users note that some of these movies are large and will take some time to download depending on your connection speed.
