MRI has no significant effect on the health of pregnant women or the development of the fetus. MRI is a test that stimulates the nuclei in the body to move and shift through changes in the external magnetic field. The MRI is a magnetic field test that stimulates the nuclei of the body to move and deviate from the magnetic distance of 0. The nuclei of the nuclei move in a directional way to image the body and check whether there are any abnormal lesions in the body. MRI is different from CT or X-ray examinations, both of which are performed by means of radiation exposure. MRI is radiation-free and does not affect the development of the fetus or the health of the pregnant woman.
