Investigation on the imaging features and value of multilayer spiral CT in diagnosis of pulmonary embolism

Objective: To investigate the diagnostic valuation of multilayer spiral CT pulmonary angiography in pulmonary embolism. Methods: A retrospective analysis 22 cases of pulmonary embolism were performed by 16 slice spiral CT diagnosis, The volume data of all cases were reconstructed for image post-processing with multi-plane reconstruction, maximum intensity projection and volume rendering. Results: Pulmonary embolism in patients with 22 cases,pulmonary artery and its branches remobilization of 22 cases were demonstrated well by MSCTA.Conclusion: The 16 slice spiral CT in the diagnosis of pulmonary embolism in a safe, rapid, high sensitivity, reliable diagnosis advantages, has been used as first choice of imaging diagnosis of pulmonary embolism diagnosis methods. It is worthy of wide clinical application.
