When you first arrive to the nuclear medicine department the technologist. There are four parathyroid glands which are usually located behind the thyroid gland and in rare cases within the thyroid gland or in the chest. Parathyroid glands are small endocrine glands in the neck that produce parathyroid hormone.
What is a parathyroid scan. When you arrive in the department you will be given a small injection of a tracer into a vein in your arm this injection has no side effects. There are two main parts to your parathyroid scan.
What will happen when you have your parathyroid scan. Parathyroid scan a parathyroid scan looks for the presence of parathyroid adenomas. Subsequently the thallium tl 201 99m tc pertechnetate thallium pertechnetate subtraction method was described which became the first widely accepted method for radionuclide imaging of the parathyroid glands.
Nuclear medicine imaging of the parathyroid glands was introduced in the late 1970s using thallium tl 201 as an imaging agent. Sestamibi is used to discriminate between single and multi gland parathyroid disease. The purpose of the sestamibi scan is to detect parathyroid adenomas in patients with sporadic primary hyperparathyroidism.
A very simple way to look at these scans is this. Procedure aims of the sestamibi scan for parathyroid disease. The parathyroids are four small hormone glands lying close to or embedded in the back surface of the thyroid gland in the front of the neck.
A parathyroid mibi scan is used in nuclear medicine to look at possible problems involving the parathyroid gland s. Tc99m sestamibi is absorbed faster by a hyperfunctioning parathyroid gland than by a normal parathyroid gland. Adequate localization of parathyroid adenoma allows the surgeon to use a minimally invasive surgical approach.
A sestamibi parathyroid scan is a procedure in nuclear medicine which is performed to localize parathyroid adenoma which causes hyperparathyroidism.
Parathyroid adenoma nuclear medicine scan. The nuclear medicine scan can be fused with the ct scan as a spect scan to increase diagnostic accuracy and aid in anatomical localization. 18f fluorocholine pet ct may also have a role 18. Ct in the past ct was more commonly used in the setting of a failed parathyroidectomy for the detection of suspected ectopic glands often mediastinal 6.
