Diagnostic Ultrasound
Neck (Thyroid)
Thyroid ultrasound is a sound wave picture of the thyroid gland taken by a hand-held instrument and translated to a 2-dimensional picture on a monitor. It is used in diagnosis of tumors, cysts or goiters of the thyroid, and is a painless, no-risk procedure.
An ultrasound is the best way to get detailed information about your thyroid gland. The scan can show: the size of any thyroid nodule and whether it is full of fluid or solid. whether a nodule has any characteristics that suggest it may be a thyroid cancer rather than a benign nodule.
Before your thyroid ultrasound, you may eat normally. No special preparation is required.
During your ultrasound, pictures of your thyroid will appear on a video screen and several images and measurements will be recorded.
After your ultrasound, you can resume your normal activities.
