Computed tomography of the thyroid

Computed tomography of the thyroid is a medical imaging procedure that uses X-ray technology to create detailed images of the thyroid gland. This non-invasive procedure is often used to diagnose and monitor conditions affecting the thyroid, such as thyroid nodules, thyroid cancer, and thyroiditis.

Overview

Computed tomography (CT) is a type of imaging technology that uses a series of X-ray images taken from different angles to create cross-sectional images of the body. When used to image the thyroid, CT can provide detailed information about the size, shape, and structure of the gland, as well as any abnormalities that may be present.

Indications

Computed tomography of the thyroid is typically performed when other diagnostic tests, such as a physical examination or blood test, suggest a problem with the thyroid. It may also be used to monitor the progress of a previously diagnosed thyroid condition. Common indications for a thyroid CT scan include:

• Suspected thyroid nodules or tumors
• Suspected thyroid cancer
• Monitoring of known thyroid conditions
• Evaluation of the thyroid prior to surgery

Procedure

During a computed tomography scan of the thyroid, the patient lies on a table that slides into the CT scanner. The scanner rotates around the patient, taking a series of X-ray images from different angles. These images are then processed by a computer to create cross-sectional images of the thyroid gland.

Risks and Complications

As with any medical procedure, computed tomography of the thyroid carries some risks. These may include:

• Exposure to radiation
• Allergic reaction to contrast material, if used
• Inaccurate results
