For the examination of pituitary tumors, it can be conducted jointly through various methods such as inquiring about the patient's medical history based on symptoms and signs, as well as conducting endocrine and radiological examinations. Currently, with the continuous advancement in modern endocrinology, the use of endocrine radiology immunodiagnostic methods allows for the direct measurement of various hormones from the pituitary and hypothalamus, and functional tests of the pituitary can be performed. This helps in understanding whether there is hyperfunction in the pituitary and target organs, and provides an effective evaluation of early diagnosis of pituitary tumors, changes before and after treatment, and treatment efficacy, which is of significant importance.
