What is transvaginal ultrasound?
In any type of ultrasound examination, a transducer sends out sound waves and receives their echoes, which are then translated into a real-time picture of the internal structures being imaged. Most often, the transducer is pressed against the skin outside the body. In some cases, however, the technologist is able to get more detailed images of particular areas of interest by placing the transducer inside the vagina. While you can request that an external ultrasound exam be performed instead, it’s important to understand that if your doctor has recommended a transvaginal ultrasound, it’s because this type of exam is likely to yield the most helpful information about your condition.
