A pituitary scan is a neuroimaging test, mostly performed with the aid of CT and MRI, that is an effective test for identifying lesions of the pituitary and peripituitary organs. This test is used to determine the size and shape of the pituitary gland, as well as the presence of pituitary tumors, pituitary occupations, and the presence of compression of the surrounding pituitary tissues. The clinician will determine the need for a pituitary scan based on the patient’s symptoms, signs, and ancillary tests. The doctor prescribes a pituitary scan application form for suspected pituitary lesions. Common symptoms include endocrine dysfunction, such as menstrual irregularities, obesity, increased appetite, panic, chest tightness, hand tremors, insomnia, fear of heat, sweating, limb hypertrophy, as well as enlarged pituitary tumors and compression of the optic nerve resulting in visual field defects, and can clarify whether there is bone resorption below the pituitary gland to the saddleback.
