Optional medical device diagnostics – depending on the results of history, physical examination, laboratory diagnostics and obligatory medical device diagnostics – for differential diagnostic clarification.
- Computed tomography (CT) – sectional imaging procedure (X-ray images from different directions with computer-based evaluation).
