What is a Thyroid Ultrasound?

A thyroid ultrasound scan is a safe and non-invasive imaging procedure used to examine the thyroid gland in the neck. It uses high-frequency sound waves to produce clear, real-time images, allowing healthcare providers to evaluate the gland’s structure and condition.

Why is it Done?

This scan is typically recommended to:

• Investigate lumps or swelling in the neck
• Detect thyroid nodules or cysts
• Monitor known thyroid conditions
• Support findings from blood tests or physical exams
• Assess changes in the size or shape of the thyroid gland

What Does it Detect?

A thyroid ultrasound can help identify:

• Solid or fluid-filled nodules
• Enlargement of the thyroid (goitre)
• Structural irregularities
• Inflammation or abnormal tissue pattern

Procedure Overview

• Duration: 20–30 minutes
• Preparation: No special preparation required
• Process: A gel is applied to the neck, and a small handheld device (transducer) is moved over the area to capture images
• Aftercare: You can return to normal activities immediately

Benefits of the Scan

• Completely painless and non-invasive
• No radiation exposure
• Quick and convenient
• Provides immediate visual insights
• Helps guide further testing or treatment if needed
