A thyroid sonogram (thyroid ultrasound) is a non-invasive imaging procedure that uses high-frequency sound waves to create detailed images of the thyroid gland. It helps diagnose thyroid nodules, cysts, goiters, and other abnormalities by providing real-time visualization of the gland’s size, shape, and structure.
Procedure Breakdown:
- Preparation:
- No special preparation is needed; patients may be asked to remove jewelry around the neck.
- The patient lies on their back with the neck slightly extended to provide clear imaging access.
- Gel Application:
- A water-based gel is applied to the neck to help transmit sound waves and improve image clarity.
- Ultrasound Imaging:
- A handheld transducer (ultrasound probe) is gently moved over the neck.
- The device emits sound waves that bounce off the thyroid, creating live images on a monitor.
- Evaluation:
- The technician or radiologist assesses the thyroid’s size, texture, and any irregularities.
- If nodules or cysts are detected, further analysis, such as a biopsy, may be recommended.
- Completion & Results:
- The gel is wiped off, and the procedure is completed within 15–30 minutes.
- A radiologist reviews the images, and results are shared with the patient’s doctor for further evaluation or treatment planning.
A thyroid sonogram is a safe, painless, and effective method for diagnosing thyroid conditions without radiation exposure.
