What is a Whole Body Iodine Scan?

Radionuclide imaging — tracking thyroid cells head-to-toe.

A Whole Body Iodine Scan is a highly specialized nuclear medicine imaging study that is performed following thyroid surgery or radioactive iodine therapy. The scan is used to assess if there is still thyroid tissue in the body and if there are thyroid cancer cells spread to other parts. The information is very important in deciding subsequent treatment and in helping monitor the results of past treatment.

The Whole Body Iodine Scan imparts useful information not available from blood markers or traditional imaging techniques. It can also help doctors assess the distribution of thyroid-avid tissue in the body, helping them decide on how to manage it.

In a Whole Body Iodine Scan, radioactive iodine is administered to the patient to image thyroid tissue and certain thyroid cancer cells throughout the body. Radioactive iodine naturally enters thyroid cells and thus has utility to locate thyroid tissue left behind and thyroid metastasis.

Indications

Why might you need a Whole Body Iodine Scan?

A whole body iodine scan is usually given to patients who are treated for differentiated thyroid cancer. The scan may also help to determine if there is any thyroid tissue remaining or if the disease returned or spread.

Papillary Thyroid Cancer

Staging and monitoring the most common form of differentiated thyroid cancer.

Follicular Thyroid Cancer

Surveillance and detection of potential spread of follicular thyroid cancer.

Follow-up after Thyroidectomy

Assess if there is any remaining thyroid tissue left in the neck bed after surgery.

Post-Radioiodine Therapy

Evaluate the treatment response and effectiveness after receiving radioactive iodine therapy.

Elevated Thyroglobulin Levels

Pinpoint the source of functioning thyroid cells when blood thyroglobulin levels rise.

Suspected Recurrence

Detect recurrent thyroid cancer at an early stage for timely intervention.

Suspected Metastatic Disease

Identify and map thyroid cancer spread to lymph nodes, lungs, bones, or other parts.

Monitoring Treatment Response

Evaluate the progress of therapy to help doctors plan subsequent management.

Long-term Surveillance

Routine cancer surveillance for long-term health and peace of mind.

Conditions Evaluated

Conditions we help evaluate.

Understanding the focus of a Whole Body Iodine Scan in thyroid cancer care.

Thyroid Cancer

Differentiated Thyroid Cancer

Commonly used in patients diagnosed with papillary or follicular thyroid cancer to assess residual disease and monitor outcomes.

Papillary & Follicular Staging
Post-Surgery

Residual Thyroid Tissue

Following thyroid surgery, small amounts of thyroid tissue may remain in the neck. The scan helps identify any remaining functioning tissue.

Identifies remaining active tissue
Surveillance

Recurrent Thyroid Cancer

In some patients, thyroid cancer may return after treatment. The scan helps detect recurrent disease at an early stage.

Early recurrence detection
Metastasis

Metastatic Thyroid Cancer

Thyroid cancer may spread to lymph nodes, lungs, bones, etc. The scan helps identify sites of metastatic disease that absorb iodine.

Treatment Response Assessment

Helps physicians evaluate the effectiveness of radioactive iodine therapy and determine if additional treatment is required.

Evaluates RAI therapy efficacy
Biochemical marker

Elevated Thyroglobulin Workup

Helps identify the location and extent of active thyroid cells when blood thyroglobulin markers are elevated.

Pinpoints rise in tumor markers

Have elevated thyroglobulin levels that require detailed clinical investigation.
Papillary Cancer Follow-up
Require routine post-treatment surveillance for papillary thyroid cancer.
Follicular Cancer Follow-up
Require routine post-treatment surveillance for follicular thyroid cancer.
Recurrence Evaluation
Need clinical evaluation for suspected recurrent disease.
Metastatic Screening
Need assessment for possible metastatic spread of thyroid disease.
Routine Surveillance
Require routine post-treatment surveillance for long-term health monitoring.
Specialist Recommendation
Referred by a physician based on pathology, blood tests, or previous imaging studies.
Before Your Scan

Preparation instructions.

Following these preparation instructions carefully helps ensure the highest diagnostic accuracy.

Follow low-iodine diet
Follow a low-iodine diet for 48 hours before the scan or as advised.
Carry blood reports
Carry fresh T3, T4, and TSH blood test reports on the day of your scan.
Disclose all medications
Inform us about all medications and supplements you are currently taking.
Avoid Thyronorm
Avoid Thyronorm and other thyroid medications before the scan, as advised by your physician.
Disclose recent CT scans
Inform us if you have recently undergone a CT scan with iodine contrast.
Disclose pregnancy status
Tell us if you are pregnant or breastfeeding, as special protocols apply.
Avoid iodine supplements
Avoid iodine-containing supplements unless specifically approved by your physician.
The Procedure

Your scan, step by step.

At Molecular Diagnostics and Therapy, we strive to make your Whole Body Iodine Scan comfortable and stress-free.

01
Tracer Administration
A small amount of radioactive iodine is administered orally 48 hours before the scan is performed.
02
Uptake Period
A waiting period of 48 hours is required to allow the iodine to be absorbed by any remaining thyroid tissue or thyroid cancer cells.
03
Gamma Camera Imaging
You lie comfortably on the imaging table while our imaging gamma camera produces detailed whole-body sweep images. This process is completely painless.
05
Expert Report — Next Day
Our experienced specialists analyze the images, and highly accurate reports are available the next day after the scan is completed.

Is a Whole Body Iodine Scan safe?

Yes, a Whole Body Iodine Scan is known to be safe and well established in nuclear medicine. Radioactive iodine doses used are tightly regulated and administered, and the protocols for administration are closely monitored.

The radioactivity passes out of the body over a period of time. Where appropriate, post-scan instructions are given to patients.

Whole Body Iodine Scans are generally not performed in pregnant women due to radiation risks to the developing infant.
If you are breastfeeding, please inform our team beforehand so we can ensure proper guidance.
No sedation is required — you remain awake and comfortable throughout the imaging.
Our patients' safety is our top priority at all times during the examination.

Understanding your results.

After the scan, our experienced Nuclear Medicine specialists carefully analyze the images and prepare a detailed report. Your scan may show:

No evidence of residual thyroid tissue — Suggests complete surgical removal and successful ablation.
Residual thyroid tissue in the neck — Small amounts of functioning tissue remaining in the neck bed.
Recurrent thyroid cancer — Early detection of localized cancer cells that have returned.
Metastatic thyroid cancer — Thyroid cancer cells that have spread to other parts of the body.
Uptake in lymph nodes — Iodine absorption in regional neck lymph nodes.
Uptake in lungs or bones — Iodine concentration in distant organs, guiding therapy planning.
Normal post-treatment findings — Expected physiologic distribution of the tracer.
