In radiologic procedures, consent is required where applicable. Which statement is most accurate?

• A. Consent must be obtained before each radiologic exam.
• B. Consent may be required depending on the procedure and patient context.
• C. Consent is never required for imaging.
• D. Consent is only required for minors.

Answer: (B)

Consent in radiologic procedures is a process that varies with what is being done and who is involved. For many routine imaging studies, a separate written consent isn’t required in every case; simply obtaining the patient’s cooperation and ensuring they understand what will happen is often enough. But when the procedure carries more risk, is invasive, uses contrast, or involves steps that alter the patient’s body, explicit informed consent is necessary. This includes explaining risks, benefits, alternatives, and answering questions, with documentation of the discussion. If the patient can’t consent—such as a minor, someone who lacks decision-making capacity, or an emergency where a surrogate is needed—consent must come from the appropriate guardian or surrogate, and in emergencies, consent may be implied to proceed if delaying treatment would cause harm. Because these requirements depend on the specific procedure and patient context, the most accurate statement is that consent may be required depending on the procedure and patient context.
