Conn Syndrome: Diagnostic Tests

Note: Diagnostic imaging before laboratory evidence of the disease is not indicated!

Optional medical device diagnostics – depending on the results of the history, physical examination, and obligatory laboratory parameters – for differential diagnostic clarification in case of a positive confirmatory test.

  • Computed tomography (CT; sectional imaging procedure (X-ray images from different directions with computer-based evaluation)) – thin-slice CT of the adrenal glands* .
  • Alternatively, magnetic resonance imaging (MRI; computer-assisted cross-sectional imaging procedure (using magnetic fields, that is, without X-rays) of the adrenal glands* .
  • Adrenal vein catheterization and determination of aldosterone concentration – for lateral localization.

* In bilateral (bilateral) adrenocortical hyperplasia, the findings are often unremarkable.
