Ultrasound for Thyroid Lesions

Ultrasound for Thyroid Lesions

Diagnosis of Thyroid Disorders

Tests that may be used to evaluate your thyroid include blood tests, radiology tests or biopsies. These tests are used to identify the characteristics of the thyroid disorder and what problems they are causing, specifically whether they are:
  • Enlarged nodules or goiters that can crowd around the wind pipe or gullet and make breathing or swallowing difficult
  • Cyst or fluid-filled nodules
  • Graves’ disease, which causes thyroid enlargement and hyperthyroidism
  • Hashimoto’s disease, where your thyroid is damaged by your immune system and hypothyroidism
  • Cancer or replicating abnormal cells

Radiology Tests

Imaging tests such as ultrasound, CT or MRI are used to
  • Work out the size of lumps or nodules in the thyroid gland
  • Visualize the consistency of the tissue within and around the gland
Imaging tests using radioactive iodine are used to
  • Review the function of thyroid nodules
