Parathyroid Scan



This scan evaluates the Parathyroid tissue.

The Procedure:

  1. You will receive an injection in your hand or arm by a Nuclear Medicine Technologist. If you are an inpatient, we may use an existing INT or IV needle site. The injection is a low level radioactive material and patients rarely have a reaction.
  2. You will be scanned immediately after the injection. Once this scan is completed you can leave, but you must return again in two hours for additional images. The Nuclear Medicine Technologist will let you know when to return.

Inpatient and Outpatient Preparation Instructions:

  1. If you are breast-feeding, pregnant, or think you are pregnant, you must inform your doctor.
  2. You should have had a serum calcium blood test before this test is performed.
  3. There is no preparation necessary for this test. You can eat and drink prior to this scan.


For your convenience we may schedule more than one test on the same day. This can be confusing because the tests may have different preparation instructions. If you are an outpatient and don’t understand the instructions please call Radiology. If you are an inpatient the nursing staff will correlate your test with the preparation.

For Your Information:

The Radiologist (x-ray doctor) will read the scan and send the results to your doctor.


There is a charge for the isotope injection that must be ordered before the scan. If it is necessary to cancel the scan, please call the Radiology department at 419-394-3335 extension 3528 as soon as possible.
