What is high-definition ultrasonography?

Also known as: high-definition ultrasound, high-resolution ultrasonography, high-resolution ultrasound

Ultrasonography, or ultrasound, is a medical imaging test performed with a handheld instrument known as a transducer. The newest models of ultrasound machines produce high-definition imagery. Examining an unborn child in the womb is a frequent use of high-definition ultrasonography, but it is also useful for examining organs close to the surface of the skin to look for problems, such as the thyroid gland.
