You must withhold thyroid medication for 6 weeks prior to the appointment. In addition, you can not have had any IV Contrast "Dye" injected within the previous 8 weeks. These medications can cause false readings and the Thyroid Uptake and Scan will not be accurate.
What to Expect:
You will be given two appointment times on the same day for this procedure. The first lasts for approximately 15 minutes. You will be greeted and escorted back to the Nuclear Medicine suite by one of our team members. Once there, your Technologist will explain the procedure, discuss your symptoms (if any) and medical history. Then the technologist will administer a capsule. The capsule is a small amount of a radiopharmaceutical designed to be taken up by your thyroid gland. You will be asked to fast (nothing to eat or drink) for 30 minutes after you take the capsule in order to let it dissolve in your stomach. After that, you do not have to fast any longer.
Your second appointment will be 6 hours later on the same day. Between parts 1 and 2 you can leave the hospital, go shopping, go home and do whatever you like. You do not need to re-register for your second appointment. You can go directly to Radiology Reception. Upon arrival, again you will be greeted and escorted to the Nuclear Medicine suite and your Technologist will assist you in getting in position on the imaging table. You will lie on your back with a small pillow placed under your neck to allow for optimum visualization of your thyroid during the scan. For maximum comfort another pillow is placed under your knees and a you are covered with a warm blanket.
Your Technologist will obtain 4 pictures of your thyroid, each image taking anywhere from 3 minutes each to 8 minutes each to acquire. This time varies for each patient, as everyone's thyroid absorbs the material in the capsule at a different rate. We estimate approximately 45 minutes for your second appointment.
Once the all images are acquired, the Technologist will evaluate the images for quality, address any issues or concerns that you may have and escort you back to the reception area. The images are read by a Radiologist (doctor) and the results are dictated, transcribed and sent to your ordering physician within 3 business days. The ordering physician will provide results to you.
