What describes a thyroid collar?

• A. A flexible lead shield that is placed securely around the neck
• B. A rigid metal shielding worn over the chest
• C. A device to hold the imaging receptor in place
• D. A collar used to support the patient

Answer: (A)

A thyroid collar is a protective shield made of lead that fits around the neck to protect the thyroid gland from scatter radiation during X-ray imaging. It’s flexible so it can snugly encircle the neck without getting in the way of the image receptor. This shielding is specifically for the neck area and is not the same as a lead apron that covers the chest, nor is it a device that holds the receptor or a support collar for the patient. The idea is to reduce radiation dose to a sensitive gland during radiography.
