Which statement about MRI radiation exposure is true?

Explanation:
MRI relies on a strong magnetic field and radiofrequency energy to image tissues, not on ionizing photons. Ionizing radiation refers to X-rays and gamma rays, which MRI does not use. Because the energy involved in MRI is non-ionizing, the exposure remains free of ionizing radiation regardless of the sequence used. That’s why the statement MRI uses no ionizing radiation is true. The other ideas would imply the presence of ionizing photons or a dependence on sequence that isn’t there.
