Also known as: high-definition ultrasound, high-resolution ultrasonography, high-resolution ultrasound
What is high-definition ultrasonography?
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.
What happens during the test?
For a high-definition ultrasound to look for problems with the thyroid gland, you will lie down on a table with your neck stretched slightly. The technician will apply a special gel to the neck, and then move the ultrasound transducer back and forth over the skin of the neck. The sound waves produce an image within your body that is produced on a computer screen, so the technician can monitor their progress during the test.
Is any special preparation needed?
No special preparation is needed for this test.
What are the risk factors?
There are no risks to high-definition ultrasonography.
