Sex determination is not an absolute with ultrasound. In the hands of an experienced Ultrasound Technologist, sex determination is usually very good after 20 weeks (external genitalia is not developed until around 18 weeks). Also, your child could be in a position that is not always good for the evaluation and visualization of the genitalia. Given these factors, one must keep in mind that sex determination is not always correct.

Medical ultrasonography (sonography) is an ultrasound-based diagnostic imaging technique.

Basically it is a technology that gives a technician the ability to take pictures of the muscles, tendons, and organs of someone with sound. It was first done in 1940 and has been used safely ever since. The technology has matured a lot since the 40's and today we get some very lifelike images.
