Imaging studies that may be considered include the following:

  • Chest radiography (for detection of an underlying pulmonary cause of SIADH)

  • Computed tomography or magnetic resonance imaging of the head (for detection of cerebral edema occurring as a complication of SIADH, for identification of a CNS disorder responsible for SIADH, or for helping to rule out other potential causes of a change in neurologic status)

See Workup for more detail.
