What is a Thyroid Scan?
A Thyroid Scan is a special type of nuclear medicine imaging procedure used to assess the activity and function of the thyroid gland. A tiny, safe amount of radiotracer (such as Technetium-99m or Radioactive Iodine I-131) is administered and naturally absorbed by thyroid tissue. A sensitive gamma camera then captures high-resolution functional images of the gland.
Function vs. Structure: While an ultrasound shows the physical structure of your thyroid, a Thyroid Scan shows how well the gland is functioning in real time, helping your doctor pinpoint areas of overactivity or underactivity.

Conditions We Help Diagnose
A Thyroid Scan provides valuable insights not obtainable through blood tests or ultrasound alone. We commonly perform scans for:
-
Hyperthyroidism
Identifies the cause of excess thyroid hormone production.
-
Graves' Disease
Shows uniformly increased tracer uptake across the gland.
-
Thyroid Nodules
Classifies nodules as hot, warm or cold.
-
Multinodular Goiter
Maps multiple overactive nodules within the gland.
-
Post-Surgery Follow-up
Checks for residual thyroid tissue after surgery.
-
Pre-RAI Planning
Essential baseline assessment before I-131 therapy.
Instructions Before Your Thyroid Scan
-
Fasting
No fasting is required before your Thyroid Scan.
-
Reports to Carry
Bring fresh T3, T4 and TSH blood test reports.
-
Neomercazole Hold
Avoid Neomercazole for 5 days before the scan.
-
Thyronorm Hold
Avoid Thyronorm for 3 weeks before the scan.
Please do not stop or change any medication without first confirming with your treating doctor.
Frequently Asked Questions
What is a Thyroid Scan used for?
We use a Thyroid Scan to evaluate the function of your thyroid gland and diagnose various thyroid disorders such as hyperthyroidism, Graves' disease, and functioning nodules.
Is the procedure painful?
No. The scan is completely painless, and most patients remain comfortable throughout the procedure.
How long does a Thyroid Scan take?
The imaging itself usually takes 20–45 minutes, although the total appointment time is 1 to 2 hours depending on radiotracer absorption time.
Is the radiation exposure safe?
Yes. The amount of radiation used is very low and considered safe for diagnostic imaging purposes.
Do I need to fast before my Thyroid Scan?
No. Fasting is not required. Please bring fresh T3, T4, and TSH blood test reports and follow medication instructions (hold Neomercazole for 5 days & Thyronorm for 3 weeks).
Can pregnant women undergo a Thyroid Scan?
We generally do not perform Thyroid Scans during pregnancy unless specifically advised by your treating physician.
What is the difference between a Thyroid Scan and a thyroid ultrasound?
A thyroid ultrasound evaluates physical structure, while a Thyroid Scan assesses how well the thyroid is functioning.
Why choose Molecular Diagnostics and Therapy?
