What is a Parathyroid Scan?

The Parathyroid Scan is a diagnostic scan to determine whether you have an abnormally functioning parathyroid gland. It is usually advised if your reports show high calcium and parathormone levels. Finding the precise location of the abnormal parathyroid gland also helps the surgeon in case surgery is planned.

 

Preparing for the scan:

  • Patients do not need to fast before the scan
  • If in doubt about pregnancy, women patients should do a pregnancy test. If positive, Nuclear Medicine is generally not recommended
  • Lactating women should pump and store their breast milk before a Nuclear Medicine scan. It is safe to breastfeed the child 24 hours after the scan
  • Wear comfortable clothing and avoid jewellery on the day of the scan

 

What to bring on the day of the scan:

  • Doctor’s prescription or note indicating the type of scan to be done
  • Entire current medical file and prescription set to be aware of  any medical conditions and allergies, including details of treatment history
  • All relevant previous reports and scan images (USG/CT neck reports)
  • History of aches/pains
  • Calcium and PTH levels. Our pathology labs also offer this service
  • Only one accompanying person is recommended
  • Home-cooked food for the patient to eat after the scan

 

Time taken:

  • Total time: 4- 5 hrs
  • Multiple scans are acquired at different time intervals

 

How is Parathyroid scan done?

A Parathyroid scan uses a radioactive material (tracer) to produce 2D and 3D images of organs and areas within the body. The changes that take place are recorded in a sequential manner. The process you will follow when you go for a Parathyroid scan is as follows:
  • When you arrive at the centre a doctor’s referral note is received and checked by the department
  • You will be asked to sign a consent form before undergoing the scan and at the same time you can address your queries with the Nuclear Medicine physician.
  • Once the formalities are completed, you need to tell your Nuclear Medicine physician about all the medications you take on a daily basis, any drug allergies or other medical conditions you have.
  • After completing all the queries, your Patient Care Co-ordinator will explain the procedure of the scan.
  • After registration, the staff nurse will prepare you for your scan and ask you to remove all sorts of metal/jewellery on you. 
  • The nurse then places a cannula in your vein to prepare for the radiotracer injection. 
  • There are two parts to the Parathyroid scan. In the first part the radiotracer is pushed in the vein through the cannula. Radiotracer helps determine the problem by highlighting the scanned area. The amount of dose given and the timing is noted. 
  • You will have to wait for 20-30 mins for the tracer to get absorbed before the scan.
  • Inside the gamma scan room you will lie on the bed which will be moved into the machine for the scan, high-count images are obtained for 10 mins after administration
  • You will be monitored through a CCTV/glass screen. Emission from the tracer is detected by the scanner and high quality images are produced by the machine.
  • After the first scan you will be given the second injection and will have to wait for upto 20 – 30 mins for the second scan to begin. The scan is for 30 minutes.
  • After the second scan, there is a waiting period of 2 hours for delayed images. After two hours you will be taken for the scan and high-count images of the neck and chest are taken for around 10-15 mins.
  • You will then be kept under observation in case any other delayed scan is required after the initial scan is reviewed by a Nuclear Medicine physician.
  • As you receive a clearance from the reviewing Nuclear Medicine physician you will be advised to leave with some safety instructions.
  • You will be advised to stay away from children and pregnant women for 24 hours and to drink lots of water/fluid after the scan to flush out the radiotracer through urine.

 

After the scan:

  • Patients can eat, drink and take medication
  • Patient is required to wait in the clinic for approximately half an hour after the scan, till the concerned staff confirms
  • It is best for the patient to not be close to children or pregnant women for the rest of the day to avoid exposing them to any radiation
  • The radiotracer leaves the patient’s body through urine or stool till 10-12 hours after the scan. Patients should drink a lot of water to help flush it out
