It bounces sound waves into the womb. The sound waves are then bounced back again and the image that they produce by bouncing around the fetus is relayed and shown on a computer screen. As they sound waves can only bounce around objects they cannot creat colours hence it is in black and white.

Why after having a pelvic ultrasound did I need to have a transvaginal ultrasound immediately?

If you are in the early stages of a pregnancy, a transvaginal ultrasound is preferred over a transabdominal ultrasound (scanning through the top of the lower abdomen) because a transvaginal ultrasound provides much more detail and accuracy in assessing a fetus. Early on in pregnancy, the baby is extremely small, only a few millimeters long in the first few weeks. A transvaginal ultrasound will allow the doctor to see the baby's heart beat, even at 5 weeks old in the womb, whereas a transabdominal ultrasound would have an extremely hard time seeing something so tiny. If you are NOT pregnant, and you had t have this type of exam, this is nothing out of he ordinary. Sometimes, during a transabdominal ultrasound, gas from your stomach and bowel can get in the way, making it very hard to see organs such as the uterus and ovaries. If you do not have a full bladder, it will be nearly impossible to obtain medically relevant images through your stomach. A transvaginal ultrasound does not need a full bladder nor does it rely so much on the absence of bowel gas. In this case, it also provides much greater detail than a transabdominal ultrasound.
