PDFAbstract
Objective This paper is to discuss the diagnostic value of 16 slices spiral CT angiography (CTA) on pulmonary artery embolism. Methods Thirty patients with pulmonary artery embolism admitted by the Out-patient Service and In-patient Department from January, 2012 to November, 2014 were selected as research subjects, 16 layers of spiral CT angiography was applied to conduct examination, and the postprocessed technology such as volume rendering, multi-plane reconstruction and maximum density projection were applied to evaluate the branch blood vessels. Results The range, location of embolism and narrowing of blood vessel luminal of 25 out of 30 patients with pulmonary embolism were dislayed clearly, accounting for 83.33% approximately, the most direct radiological signs of pulmonary artery embolism included intra-cavity filling defect, complete blocking, blood vessel wall thickening. And the indirect radiological signs included pulmonary infarction, pulmonary hypertension, Mosaic sign, pleural effusion, bronchiectasis and embolism in right ventricle or right atrium, etc. Conclusions CTA delivers rapid and noninvasive advantages with high diagnosis rate in the diagnosis of pulmonary embolism, facilitating the formulation and evaluation of clinical physicians on treatment schemes.
