MRI is radiation-free and does not cause radiation damage to the human body.
MRI is a way of using a strong external magnetic field and the hydrogen nuclei in the human body to produce magnetic resonance phenomena when specific radio frequency pulses are applied, and ultimately imaging is done through specialized equipment. Therefore, there is no need to worry about radiation damage.
Magnetic resonance examination has high resolution, can clearly reflect the internal structure of the human body, better localization and characterization of the lesions, the diagnosis of disease has a high clinical value.
However, it should be noted that metal objects carried on the body need to be removed before the MRI examination. The magnetic field generated by MRI during the examination will attract metal objects, which may easily injure the body and the equipment by mistake, or affect the examination results.
