Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics, and obligatory medical device diagnostics – for differential diagnostic clarification.
- ECG (electrocardiogram) – indicates the conduction of excitation of the heart.
- Echocardiography – ultrasound examination of the heart.
- Computed tomography (CT) – sectional imaging procedure (X-ray images taken from different directions with computer-based evaluation), in which the central nervous system, but also the abdominal organs can be well represented
- Magnetic resonance imaging (MRI) – computer-assisted cross-sectional imaging method (using magnetic fields, that is, without X-rays); particularly well suited for changes in the spinal cord and brain.
- Abdominal sonography – ultrasound of the abdominal organs.
