When might radiographic procedures be contraindicated for a patient?

• A. If the patient simply wants not to do it.
• B. When the equipment is old.
• C. In all cases for pediatric patients.
• D. If the risks outweigh benefits, such as in certain pregnancy cases or when patient condition precludes safe imaging.

Answer: (D)

The important idea is that radiographic studies are done only when the expected diagnostic benefit justifies the risks and procedures involved, following the ALARA principle to keep radiation exposure as low as reasonably achievable. This means imaging is contraindicated when the risks outweigh the benefits, such as in pregnancy, where fetal radiation exposure can cause harm, or when the patient’s condition makes safe imaging impractical or unsafe. Consent and patient willingness matter, but a patient’s simple refusal isn’t in itself a medical contraindication, and equipment age doesn’t automatically prevent imaging. When the potential harms exceed the possible benefits, the study should be deferred or alternative methods used.
