How to diagnose pituitary tumor

MRI is the first choice for the diagnosis of pituitary adenomas. It can clearly show the shape, size and relationship with surrounding tissues. The detection rate of pituitary microadenomas is high. Computed tomography (CT) can also be used for examination, but it is not as good as MRI in showing the fine structure of the pituitary gland. 2. Endocrine examination helps to determine the type of pituitary tumor and its impact on endocrine function by detecting various hormone levels in the blood, such as growth hormone, prolactin, thyrotropin, adrenocorticotropin, etc. For example, prolactin levels in patients with prolactinomas are usually significantly elevated.3. Visual acuity and visual field examinationsBecause pituitary tumors may compress the optic nerve, resulting in decreased vision, visual field defects, etc. Visual acuity and visual field examination can assess whether the optic nerve is damaged, which is of great significance for the judgment of the disease and the formulation of treatment plans. 4. Pathological examination Pathological examination of surgically removed pituitary tumor specimens is the" gold standard" for determining the nature of the tumor. Pathological analysis can determine the type of tumor, cell characteristics, etc., and provide a basis for subsequent treatment and prognosis evaluation. The above examination methods usually need to be combined to improve the accuracy and comprehensiveness of pituitary tumor diagnosis. The doctor will make an accurate diagnosis based on the patient's specific symptoms, signs and examination results, and formulate an individualized treatment plan.
