Evaluate palpable masses within or adjacent to the thyroid. The scan can usually distinguish between solid and cystic structures.
Determine whether the thyroid gland is enlarged or has a diffuse abnormality. A thyroid ultrasound may also be used to monitor the size and vascular perfusion of the thyroid gland during treatment. Abnormal parathyroid glands may be enlarged and detectable by ultrasound.
Ultrasound guided thyroid biopsy or fine needle aspiration biopsy (FNAB) may be recommended by a Radiologist eg following detection of a suspicious nodule at diagnostic ultrasound. FNAB may be requested by an Endocrinologist or a Surgical Specialist following clinical assessment of thyroid disease.
Scrotal ultrasound is performed to:
Evaluate a mass or pain in the testes.
Identify and monitor infection or inflammation of the testes or epididymis
