Introduction
Pituitary contrast-enhanced imaging is used to detect lesions involving the pituitary gland and its surrounding structures. This technique—typically performed using magnetic resonance imaging (MRI)—assesses whether organic abnormalities are present in the pituitary and adjacent tissues, including changes in pituitary size and morphology, inflammation, presence of space-occupying tumors, or atrophy. This method holds significant diagnostic value for conditions such as pituitary adenomas, central diabetes insipidus, and pituitary apoplexy.
Pituitary enhancement imaging is primarily a method used to evaluate pituitary abnormalities.
The pituitary gland is generally the most complex endocrine organ in the body, producing hormones that regulate the growth of bones and tissues, as well as influencing endocrine activities, including gonadotropins, oxytocin, prolactin, and others. Pituitary enhancement imaging is mainly used to detect lesions in the pituitary gland and surrounding areas. For example, magnetic resonance imaging (MRI) can be used to observe whether organic abnormalities exist in the pituitary and adjacent tissues, including changes in the size and shape of the pituitary, inflammation, space-occupying lesions such as tumors, atrophy, and other abnormalities. This technique is highly valuable in diagnosing conditions such as pituitary adenomas, central diabetes insipidus, pituitary apoplexy, pituitary abscesses, and lymphocytic hypophysitis.
If MRI is used for pituitary enhancement imaging, it is generally not recommended for pregnant women or patients with metallic implants in the area being examined, or those with implanted devices such as cardiac stents or cochlear implants. Such patients may instead undergo pituitary CT scanning to assess the specific condition of the pituitary gland.
