[MRI of the pituitary gland: indications and results in gynaecology and in obstetrics].

MRI is the sole radiological examination to be obtained if abnormal menses, galactorrhea or anovulation evokes the diagnosis of prolactinoma. Nevertheless, iatrogenic hyperprolactinemia or presence of big prolactin has to be ruled out before MRI is asked for. MRI of the pituitary gland must be technically optimal; analysis of the images has to be directed by clinical and biological data.
