This guideline will assist individual departments in the formulation of their own local protocols. The purpose of this guideline is to assist specialists in nuclear medicine and radionuclide radiology in recommending performing interpreting and reporting radionuclide thyroid scans. Tc 99m pertechnetate thyroid scan is a functional nuclear medicine study used to assess the thyroid gland the uptake of the pertechnetate anion similar in chemical physical characteristics to the iodide ion in the thyroid parenchyma is mediated by the nis sodium iodide symporter.
Background information and definitions thyroid uptake determination is the measurement of the fraction of an administered amount of radioactive iodine. The purpose of this guideline is to assist nuclear medicine practitioners in recommending performing interpreting and reporting the results of thyroid uptake measurements. This article attempts to highlight the key information mentioned in those documents in a manner relevant to current general practice.
Guidelines provided by the society of nuclear medicine 1 and the american college of radiology 2 are exhaustive with regard to indications and medicines substances to avoid with thyroid scans. It can spot lumps or inflammation or to investigate the cause of an overactive thyroid. The first type a thyroid scan produces a picture of the gland.
Both assess the health of your thyroid a gland in your neck. There are two types of thyroid nuclear medicine tests. What are thyroid nuclear medicine tests thyroid scan and uptake.
The purpose of this is to allow adequate time for the radioisotope to be taken up by the thyroid. This will be followed by a scan 20 mins after the radioisotope injection. The thyroid scan in the nuclear medicine spect ct department you will receive a radioisotope injection.
The procedure only takes minutes and. The test requires a patient to ingest a small amount of radioactive iodine many hours before testing. The test is necessary to detect a number of conditions including hyperthyroidism goiter and thyroid cancer.
A nuclear medicine thyroid scan is a diagnostic tool used to determine a patient s thyroid function.
Nuclear medicine normal thyroid scan. A nuclear medicine thyroid scan is necessary to diagnose the specific disorder. Unlike other forms of medical imaging such as mri or pet scans nuclear medicine scans have the advantage of showing metabolic function in real time. For a nuclear medicine thyroid scan the scan measures the rate at which the thyroid absorbs iodine. Thyroid scans are usually performed on an outpatient basis in the nuclear medicine department of a hospital.
They can be administered by a nuclear medicine technologist. A nuclear medicine thyroid scan uses a radioactive medication radiopharmaceutical to take pictures or images of the thyroid gland. The radiopharmaceutical is injected into a vein usually in the arm and enters the thyroid gland from the circulating blood. It is detected by a special gamma camera that takes images and provides information.
