Thyroid Scan in Mumbai

What is Thyroid Scan?

A Thyroid scan is a specialized diagnostic scan using radioactive tracers and a gamma camera for examining how your thyroid gland is functioning.

Preparing for the scan:

  • You should stop taking thyroid medicines 3 days in advance of the day of the test and also avoid cough syrups, lotions, medications (IV contrast for CT scan)and food items containing iodine.

  • Patients do not need to fast before the scan.

  • Women should tell their doctors if there is any chance they may be pregnant. If in doubt, make sure to take a pregnancy test before performing the scan. If the pregnancy test is positive, Nuclear Medicine scan is generally not recommended.

  • If a woman is lactating it is absolutely necessary to pump and store your breast milk before a Nuclear Medicine scan. It is safe to breastfeed your child again after 24 hours.

  • It is recommended that you are accompanied by one relative to help you during the course of the scan.
  • Wear comfortable clothing and avoid  jewellery.

What to bring on the day of the scan:

  • Entire current medical file and prescription set to be aware of  any medical conditions and allergies, including details of surgeries/procedures/chemo/radiation.

  • All relevant previous reports and scan images (thyroid hormone levels T3,T4 and TSH, USG neck reports.)

  • Only one accompanying person is recommended.

  • Home-cooked food for the patient to eat after the scan.

Time taken:

  • Total time: 1 -1.5 hrs approx.

  • Waiting time after injection: 20- 30 min.

  • Scan duration: 15 mins.

How is Thyroid scan done?

A Thyroid 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 Thyroid scan is as follows:

  • When you arrive at the centre a doctor’s referral note is received and checked by the departmetn.

  • 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 to remove all sorts of metal/jewellery on you.

  • The nurse then places a cannula in your vein to prepare for the radiotracer injection. The radiotracer is pushed in the vein through the cannula on the gamma scan table. 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. 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.  Imaging generally takes around 25-30 minutes.

  • After the scan you will be kept under observation in case any delayed scan is required after the initial scan is reviewed by a Nuclear Medicine physician.

  • After receiving 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.
