What are contact shields?

What are contact shields?

• A. Flat or shaped and placed directly on patient.
• B. Suspended over region of interest and cast a shadow, used in OR.
• C. Mounted on walls to shield the entire room.
• D. Worn by the radiology technologist.

Answer: (A)

Contact shields are protective devices placed directly on the patient’s skin to reduce radiation dose to underlying sensitive tissues during imaging. They are flat or shaped to fit the anatomy and sit in direct contact with the patient so they attenuate part of the primary beam or scattered photons before reaching those tissues, lowering exposure without significantly compromising diagnostic quality when used appropriately. This direct-on-patient approach is what distinguishes them from shields that hang above the patient to cast a shadow, shields mounted on walls for room-wide protection, or protective gear worn by the technologist. As with any shielding, placement should avoid obscuring the area of clinical interest and be used only when clinically justified.
