Is head MRI harmful to people? Does it affect life?
No harm.

The application of magnetic resonance imaging (MRI) has become a common image examination method. As a new imaging technique, magnetic resonance imaging will not affect human health. Because nuclear magnetic resonance is magnetic field imaging, it is not radioactive, so it is harmless to human body.

Although MRI is unique in screening early lesions, any examination is limited. For example, some patients are not suitable for MRI, so don't overdo it. Any patient should be examined according to the doctor's advice. Don't think that the more expensive the image examination, the better. Only the exam that suits him is the best.

Because metals can interfere with the external magnetic field, patients must remove all metal objects from their bodies before doing MRI. Do not wear watches, metal necklaces, dentures, metal buttons, metal contraceptive rings and other magnetic objects for MRI examination.

In addition, wearing a pacemaker and having paramagnetic metal implants in the body, such as metal clips, stents, steel plates, screws, etc., can not be examined by magnetic resonance imaging. Upper abdomen (such as liver, pancreas, kidney, adrenal gland, etc.). Be sure to check on an empty stomach, but you can drink enough water before the check, which is conducive to a clearer boundary between the stomach and the liver and spleen.
