MRI is mainly able to make a certain tissue and part of the human body resonate in the space of a strong magnetic field, so that the disordered hydrogen nuclei are arranged in accordance with the direction of the external magnetic field. This is then converted into MRI image information through digital reconstruction techniques, which can be used to diagnose pituitary disorders. Contraindications for MRI include installation of pacemakers, metal foreign bodies in the body, critically ill patients with life-threatening conditions, and patients with claustrophobia.
