Optional medical device diagnostics – depending on the results of the history, physical examination, and obligatory laboratory parameters – for differential diagnostic clarification.
- Abdominal sonography (ultrasound examination of abdominal organs) – for basic diagnostics.
- Electrocardiogram (ECG; recording of the electrical activity of the heart muscle) – recording of the current waveform of the heart.
- Computed tomography (CT) of the abdomen (abdominal CT) – if pulmonary embolism or Budd-Chiari syndrome (thrombotic occlusion of the hepatic veins) is suspected.
- Computed tomography of the thorax/chest (thoracic CT) – if pulmonary embolism or Budd-Chiari syndrome is suspected.
