Parathyroid ultrasound and scintigraphy

Diagnostic procedure

One of our doctors will take plenty of time to fully discuss your symptoms, any previously performed tests and treatments, as well as the procedure of the planned examination.

The following step is an ultrasound of your thyroid gland. This will determine the size of the thyroids, thyroid tissue texture, and, if nodules are found, they can be measured and documented. For identifying lumps/nodes, it is particularly useful to move on to a thyroid scintigraphy.

Parathyroid scintigraphy involves an injection of a trace of a radioactive substance into your arm via an IV. The substance will be taken up by the thyroid cells and by the parathyroid in a few minutes. While the thyroid quickly eliminates the substance, it remains in the parathyroids for a longer time, and the parathyroids provide increasing contrast in the scan. The radiation exposure is comparable with that of a CT scan. These substances are easily tolerated. There has never been any report of an allergic reaction.

After about 15 min for the substance to take effect, you will lie on your back with the “gamma camera” positioned over your head. It will then perform the scan. This machine is not a closed tunnel. It is open to each side, and makes no noise.Therefore, patients suffering from claustrophobia tolerate the process well. Throughout the examination, one of our medical technicians will assist you and remain within hearing distance.

About 1½ hours later, another scan will be taken. This time, the camera also slowly rotates around your head. This machine is not a closed tunnel. It is open to each side, and makes no noise. Therefore, patients suffering from claustrophobia tolerate the process well. Throughout the examination, one of our medical technicians will assist you and remain within hearing distance.

The resulting images will be printed out and given to the consulting doctor.

Your doctor will discuss the results with you during a final consultation. Usually, you will be able to take the medical report and the images with you when you are leaving the clinic.
