Acromegaly: Diagnostic Tests

Obligatory medical device diagnostics.

  • Magnetic resonance imaging of the skull (cranial MRI, cranial MRI, or cMRI): thin-slice images of the sella turcica in coronal and sagittal slice direction in T2 and T1 weighting with and without contrast medium – in 99% of cases, a pituitary tumor (tumor of the pituitary gland) is detectable
  • Perimetry (visual field measurement) – if growth of the pituitary tumor is suspected beyond the sella turcica (Turk’s saddle; bony depression of the skull base at the level of the nose and in the middle of the skull): to determine possible visual pathway lesions (detection of visual field loss due to compression of the optic chiasm: bitemporal hemianopsia/visual disturbance with loss of both temporal visual fields).
