True or False: A thyroid collar is always recommended for every radiographic view?

True or False: A thyroid collar is always recommended for every radiographic view?

• A. True
• B. False; collars may interfere with imaging or not required in all views.
• C. True, except for panoramic views.
• D. False; shielding is advised in many views, but collars may interfere with imaging or are not required according to current guidelines.

Answer: (B)

The idea being tested is that protection must be balanced with image quality. A thyroid collar helps reduce radiation to the thyroid, but it isn’t always appropriate for every radiographic view. In some views, especially certain extraoral projections, the collar can sit in or near the X-ray beam and cast a shadow or interfere with the area being imaged, which can degrade diagnostic detail or require a repeat exposure. For other views, shielding may be unnecessary because the field of view or technique already limits exposure or because the collar would compromise the image. So shielding is used selectively, not universally for every view, making the statement false.
