Thyroid imaging (including vascular flow, when performed); with single or multiple uptake(s) quantitative measurement(s) (including stimulation, suppression, or discharge, when performed)

Thyroid imaging, commonly known as a thyroid scan, is a specialized nuclear medicine procedure designed to assess the anatomical and functional characteristics of the thyroid gland. This imaging technique involves the administration of radioactive iodine isotopes, which can be delivered either orally in liquid or capsule form or intravenously. The choice of administration route influences the timing of the imaging; if the radioactive tracer is ingested, the imaging is typically conducted several hours to 24 hours later, allowing sufficient time for the tracer to localize within the thyroid tissue. Conversely, if administered intravenously, imaging occurs approximately 30 minutes post-injection. During the procedure, the patient is positioned supine on an examination table with their head tilted back to optimize visualization of the thyroid gland. A gamma camera is utilized to capture a series of images, which may also include the vascular flow of the thyroid, if indicated. Following the imaging, a physician reviews the captured images and generates a comprehensive written report detailing the findings. Thyroid imaging can be performed in conjunction with thyroid uptake studies, which evaluate the functional capacity of the thyroid gland by measuring the absorption of iodine. This dual approach provides critical insights into both the structure and function of the thyroid, aiding in the diagnosis and management of various thyroid disorders.
