If your doctor has recommended a thyroid scan, you may be wondering what it checks and why it is needed. At Meera 4D Scans Madurai, we perform accurate, detailed thyroid ultrasound scans — giving you clear, reliable results with compassionate care.
What is a Thyroid Scan?
A thyroid scan is a specialised ultrasound imaging of the thyroid gland — a butterfly-shaped gland located at the front of your neck. The scan examines the size, shape, structure, and any abnormalities of the thyroid gland in detail. At Meera 4D Scans Madurai, we use high-resolution ultrasound technology to provide the most accurate thyroid assessment.
At Meera 4D Scans Madurai, our experienced sonologists perform thyroid scans using advanced ultrasound technology — delivering accurate, detailed results for every patient with compassionate care.
Why is Thyroid Scan Important?
A thyroid ultrasound scan is one of the most reliable diagnostic tools to assess thyroid health because:
- Detects thyroid nodules — lumps or swellings in the gland
- Identifies thyroid enlargement (goitre)
- Assesses thyroid cysts — fluid-filled sacs
- Screens for early signs of thyroid cancer
- Evaluates thyroid blood flow using Doppler
- Guides biopsy procedures when needed
- Monitors known thyroid conditions over time
When Should You Get a Thyroid Scan?
Your doctor at Meera 4D Scans Madurai may recommend a thyroid scan if you experience any of the following:
| Symptom / Condition | Why Thyroid Scan is Needed |
|---|---|
| Neck swelling or lump | Detect nodules or goitre |
| Unexplained weight gain or loss | Assess thyroid function |
| Fatigue and weakness | Rule out thyroid disorders |
| Abnormal thyroid blood test | Confirm and evaluate findings |
| Family history of thyroid disease | Early screening and detection |
| Difficulty swallowing | Check for thyroid enlargement |
| Pregnancy | Monitor thyroid health during pregnancy |
What Does Thyroid Scan Check?
- Thyroid Size — length, width, and volume of both lobes
- Thyroid Nodules — size, number, and characteristics
- Thyroid Texture — homogeneous or heterogeneous gland
- Cysts — fluid-filled vs solid lesions
- Blood Flow — Doppler assessment of vascularity
- Lymph Nodes — nearby neck lymph node assessment
- Isthmus — the connecting bridge between thyroid lobes
What is the Normal Size of Thyroid?
One of the most common questions asked at Meera 4D Scans Madurai is — what is the normal thyroid size on ultrasound?
| Measurement | Normal Range |
|---|---|
| Each lobe length | 4 – 6 cm |
| Each lobe width | 1.5 – 2 cm |
| Each lobe thickness | 1.5 – 2 cm |
| Total thyroid volume | 6 – 20 ml (adults) |
| Isthmus thickness | Less than 3 mm |
Important: A thyroid nodule smaller than 1 cm is usually not concerning. However, any nodule detected must be assessed by our specialist sonologists at Meera 4D Scans Madurai — size alone does not determine risk.
Conditions Detected by Thyroid Scan
- Goitre — enlarged thyroid gland
- Thyroid Nodules — solid or cystic lumps
- Hashimoto's Thyroiditis — autoimmune thyroid condition
