CT Thyroid Shields, when used for the soft tissues of the neck, offer a 60% dose savings to the radiosensitive thyroid gland during CT procedures. Shield consists of a thin (1mm) piece of bismuth impregnated synthetic rubber and features a curved notch in the center to ensure proper positioning. Lateral bow ties are also attached to the inferior flaps of the shield to accommodate larger necks or larger thyroid glands that extend beyond the clavicle or sternum. Adhesive back holds the shield firmly in place as patient breathes and swallows.
