Application of multi-slice spiral CT in the diagnosis of pulmonary hypertension / 中国医学科学院学报

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the utility of multi-slice spiral CT in the diagnosis of pulmonary hypertension.</p><p><b>METHODS</b>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), portal-pulmonary 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.</p><p><b>RESULTS</b>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).</p><p><b>CONCLUSION</b>CTPA can accurately diagnose pulmonary hypertension and thereby provide useful information for the etiological diagnosis.</p>
