Indications include the following:
To confirm the clinical suspicion of a thyroid nodule, precisely measure size, and determine radiographic characteristics.
Colloid or “comet tail artifact” usually points to benign disease.
Microcalcifications or irregular shape/borders are suspicious for malignancy.
To detect local recurrence in thyroid cancer.
Not routinely done in the evaluation of hyper- or hypothyroidism.

Re: THYROID/NECK ULTRASOUND mtniharika - 09-11-09 15:38 Benefits:
Most ultrasound scanning is noninvasive (no needles or injections) and is usually painless.
Ultrasound is widely available, easy-to-use and less expensive than other imaging methods.
Ultrasound imaging uses no ionizing radiation.
Ultrasound scanning gives a clear picture of soft tissues that do not show up well on x-ray images.
Ultrasound causes no health problems and may be repeated as often as is necessary.
Ultrasound provides real-time imaging, making it a good tool for guiding minimally invasive procedures such as needle biopsies and needle aspiration.
Risks:
For standard diagnostic ultrasound there are no known harmful effects on humans.
