Tests used to diagnose pituitary tumors

  • A physical exam and medical history will be taken to assess any symptoms you have along with your family history.
  • Hormone levels are tested to determine whether a tumor is causing changes to hormones. These may include tests to gauge whether a tumor is causing abnormal secretion of substances including: growth hormones, insulin-like growth factor-1, follicle-stimulating hormones, adrenocorticotropic hormones, gonadotropin and prolactin.
  • Imaging tests may be used to gauge the size of the tumor and structures that may be involved with the tumor's growth, including:
    • MRI uses magnets and radio waves to create a series of pictures of the brain and nearby structures.
    • CT scan uses X-rays to provide detailed images of brain structures, revealed as thin cross-sections.
