Thyroid scan is an imaging test that evaluates the size, shape, and function of the thyroid gland. It uses small amounts of radioactive material to produce detailed images, helping diagnose various thyroid disorders.
Other Names for the Test:
- Thyroid Scintigraphy
- Thyroid Imaging
- Radioactive Iodine Uptake (RAIU) Scan
Purpose
- Diagnose Thyroid Disorders: Detects conditions like hyperthyroidism, hypothyroidism, thyroid nodules, and goiters.
- Assess Thyroid Function: Evaluates how well the thyroid is functioning and its ability to uptake iodine.
- Identify Thyroid Nodules or Masses: Differentiates between benign and malignant nodules.
- Monitor Thyroid Treatments: Tracks progress after treatments like radioactive iodine therapy or surgery.
- Detect Thyroid Cancer Spread: Identifies metastasis in cases of thyroid cancer.
Preparation
- Inform Your Doctor: Share your medical history, especially if you’re pregnant, breastfeeding, or allergic to iodine.
- Avoid Certain Medications: Stop taking medications that interfere with thyroid function (like thyroid hormones or antithyroid drugs) as instructed by your doctor.
- Dietary Restrictions: Follow any specific dietary guidelines, such as avoiding iodine-rich foods, as directed.
- Fasting: You may need to fast for a few hours before the test.
- Remove Metal Objects: Avoid wearing jewelry or clothing with metal, as they can interfere with imaging.
