A parathyroid scan is used to detect any abnormalities within the parathyroid glands. Parathyroid glands are located behind the thyroid gland in your neck, and they regulate the amount of calcium in your body.
A parathyroid scan can be scheduled at:
A parathyroid exam can take up to 4 or 5 hours. This time allows for two sets of images to be taken, with a 2.5 to 3.5 hour wait between sets.
During your exam, a small amount of radioactive tracer will be injected into a vein in your arm. The tracer allows your parathyroid glands to be seen by the nuclear medicine camera. After 10 minutes, you will be positioned on your back and images will be taken for approximately 20 minutes. A second set of images will be taken 2.5 to 3.5 hours later, and this imaging process will take another 30-45 minutes.
Following the exam, your images will be interpreted by one of our board-certified radiologists. The findings will be sent to your healthcare provider who will then contact you to discuss the results.
Unless directed otherwise, you may drive, resume your normal diet, exercise and take all prescribed medications after your appointment.
