Abstract Objective：To study the clinical value of the CT plain scan and enhanced scan is applied to cor pulmonale pulmonary hypertension.Method： 40 patients with cor pulmonale in the hospital from November 2012 to November 2013 were selected as the research object， one of the group of 20 patients with radiation chest check the radiographic inspection group， another group of 20 cases by chest CT scan and enhanced scan CT inspection group， two groups of patients were checked before and after therapy. before and after treatment the main pulmonary artery， left and right pulmonary artery diameter changes of the two groups were compared.Result：The diameter of the pulmonary artery， left and right pulmonary artery： diagnosis by radiation measurement results compared before and after the treatment lines had significant difference（ P<0.01）， but lower right pulmonary artery of stem diameter of 15 mm were 12 cases（ 60%）， show the X-ray measurement right pulmonary artery stem diameter for diagnosis of lung pulmonary hypertension was of certain clinical value， but its specificity was poor. CT plain scan and enhanced scan results all lines had significant difference （P<0.01）， in the lower right pulmonary artery all stem diameter 15 mm or higher， significantly higher than that of radiographic inspection group（ P<0.01）， and strong specificity.Conclusion：CT examination is applied to the diagnosis of pulmonary hypertension and cor pulmonale therapeutic effect evaluation of clinical value.
