Thyroid Scan: Role in Thyroid Cancer Diagnosis & Function Assessment

A thyroid scan is a diagnostic imaging test that uses a radioactive tracer to examine the thyroid gland. This imaging technique helps doctors assess the size, shape, and function of the thyroid gland.

It is commonly used to detect thyroid nodules, assess thyroid function, and identify thyroid cancer.

During a thyroid scan, a small amount of radioactive iodine is either swallowed or injected into the body. The thyroid gland absorbs this radioactive substance, which allows a special camera to capture images of the thyroid gland.

The images produced by the thyroid scan help doctors evaluate the structure and function of the thyroid gland.

Thyroid scans are often used in conjunction with other diagnostic tests, such as blood tests and ultrasound imaging, to provide a comprehensive assessment of thyroid health. These scans are safe and non-invasive, with minimal discomfort for the patient.

What is the Purpose of Performing a Thyroid Scan Test?

The primary purpose of a thyroid scan is to evaluate the thyroid gland for abnormalities such as nodules, inflammation, or cancer.

Thyroid scans are particularly useful in identifying thyroid nodules, which are small lumps that can develop in the thyroid gland.

Thyroid scans are also used to assess thyroid function by measuring the amount of radioactive iodine absorbed by the thyroid gland.

This information helps doctors determine if the thyroid gland is functioning properly or if there are any abnormalities that need further evaluation.

In cases where thyroid cancer is suspected, a thyroid scan can help doctors identify the presence of cancerous cells in the thyroid gland. By detecting thyroid cancer early, patients can receive timely treatment and improve their prognosis.

What are the Costs of Thyroid Scan Tests in India?

The cost of a thyroid scan in India can vary depending on the location, healthcare facility, and additional services included in the test. On average, a thyroid scan can range from Rs. 2000 to Rs. 5000 in India.

Factors that can influence the cost of a thyroid scan include the type of radioactive tracer used, the expertise of the healthcare provider, and any additional imaging or consultation fees.

Patients are advised to check with their healthcare provider or insurance company for specific pricing information.

What is the Normal Range and All Values of Thyroid Scan?

The normal range for a thyroid scan depends on the specific parameters being measured, such as the amount of radioactive iodine absorbed by the thyroid gland or the size of any nodules detected.

Parameter	Normal Range
Radioactive Iodine Uptake	10-30% at 24 hours
Thyroid Nodule Size	Less than 1 cm in diameter
Thyroid Function	T3: 100-200 ng/dL, T4: 4.5-11.2 mcg/dL, TSH: 0.4-4.0 mIU/L

Frequently Asked Questions

What is a thyroid scan?

It is important to note that the interpretation of thyroid scan results should be done by a qualified healthcare provider, who can provide further guidance based on individual patient characteristics and medical history.

What Do High Thyroid Scan Levels Indicate?

High thyroid scan levels can indicate hyperthyroidism, a condition where the thyroid gland produces too much thyroid hormone. This can be caused by conditions such as Graves' disease, thyroid nodules, or thyroiditis.

What Do Low Thyroid Scan Levels Indicate?

Low thyroid scan levels can indicate hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. This can be caused by conditions such as Hashimoto's thyroiditis, thyroid surgery, or iodine deficiency.

How does a thyroid scan work?

During a thyroid scan, you will swallow a small amount of radioactive iodine or technetium. A special camera then takes images of your thyroid gland to evaluate its function and detect any abnormalities.

Why is a thyroid scan done?

A thyroid scan is done to check the size, shape, and function of the thyroid gland.

Is a thyroid scan safe?

Yes, a thyroid scan is considered safe as it involves minimal radiation exposure.

What types of thyroid problems can a scan detect?

A thyroid scan can detect various thyroid problems such as nodules, inflammation, overactive or underactive thyroid glands, and thyroid cancer.

Do I need to prepare for a thyroid scan?

No special preparation is usually needed for a thyroid scan. Just inform your healthcare provider if you are pregnant, breastfeeding, or taking any medications.

How long does a thyroid scan take?

A thyroid scan typically takes about 30-60 minutes to complete.

What is the difference between a thyroid scan and an ultrasound?

A thyroid scan uses radioactive iodine to evaluate thyroid function and structure, while an ultrasound uses sound waves to create images of the thyroid gland's size and structure.

Are there risks associated with thyroid scans?

Thyroid scans are generally safe. The risks are minimal and may include a slight risk from the small amount of radiation exposure during the test.

What should I expect after a thyroid scan?

After a thyroid scan, you can expect to resume your normal activities immediately. The radioactive material used during the scan will naturally leave your body over time.
