ABSTRACT: Objective To evaluate the utility of multi-slice spiral CT in the diagnosis of pulmonary hypertension. Methods The clinical and multi-slice spiral CT data of 22 patients with pulmonary hypertension were retrospectively analyzed. The diagnoses included chronic thromboembolic pulmonary hypertension (CTEPH) (n=9), primary pulmonary hypertension (PPH) (n=7), connective tissue diseases (n=2), portopulmonary hypertension (n=2), eosinophilia-myalgia syndrome (n=1), and fibrosing mediastinitis (n=1). Lung parenchyma, such as ground-glass opacity,mosaic attenuation and septal thickness, mediastinum, pulmonary vascular,right ventricular enlargement and interventricular septum displacement were evaluated on CT. Results CT pulmonary angiography (CTPA) accurately diagnosed 95% of pulmonary hypertension and the signs of right ventricular dysfunction. Pulmonary embolism was found in 9 patients. The incidence of mosaic attenuation was significantly higher in CTECH than in PPH (P=0.034). Conclusion CTPA can accurately diagnose pulmonary hypertension and thereby provide useful information for the etiological diagnosis.
