Differential Diagnosis of Pulmonary Hypertension With Automated Image Analysis

The aim of the study is to determine relevant morphologic parameters of the lung vasculature for the differentiation between different groups of patients with pulmonary hypertension (PH) by thoracic computer tomography (CT). In this pilot study patients undergoing right heart catheterization will be investigated by thoracic CT and special software to determine morphologic readouts. The investigators expect that using this non-invasive method, parameters relevant for the differentiation of the patients with PH can be determined.
