Sample item

Why must patients be screened for some implanted devices before MRI?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. The strong magnetic field can move, heat, or malfunction incompatible devices

MRI uses strong static and changing magnetic fields, so some implants, foreign bodies, and devices may be unsafe or require protocol modification. Device-specific compatibility must be checked.

Option by option

  • A. The strong magnetic field can move, heat, or malfunction incompatible devices (correct)

    Correct. Magnetic-field interaction can create serious device or tissue hazards.

  • B. MRI uses ionizing radiation that fractures metal

    MRI does not use ionizing radiation.

  • C. Screening is only needed for dental fillings

    Screening includes more than dental material.

  • D. MRI always causes kidney stones

    Kidney stones are not a routine MRI consequence.
