Thyroid Uptake & Scan: What It Is, Purpose, Procedure & Results
Jul 12, 2024 · A thyroid uptake and scan is a nuclear medicine imaging test that healthcare providers use to check the health and function of your thyroid. It can help diagnose and monitor several conditions, including hyperthyroidism and thyroid nodules.
What are thyroid scans and uptake tests for? - Patient
Oct 15, 2024 · Thyroid scans and uptake tests use special chemicals called radionuclides. A radionuclide (sometimes called a radioisotope or isotope) is a chemical which emits a type of radioactivity called gamma rays.

Which Radioisotope is Used for Diagnosing Thyroid Disorders?
Taken orally in small doses, I-131 is absorbed by the thyroid and traced using imaging techniques like a gamma camera to assess conditions such as hyperthyroidism, hypothyroidism, and thyroid cancer. Another option is Technetium-99m (Tc-99m), which emits less radiation and is preferred in some cases for imaging thyroid function and structure.
We put together a short review by compiling our experience of common ways to efectively utilize radioisotope techniques in thyroid clinics along with literature review from current guidelines in a most simple and easy to understand way for the clinician.
