Abstract

Objective To explore the value of pulmonary artery CTA combined with CT vengraphy in the diagnosis of pulmonary embolism. Methods Fifty-six suspected pulmonary embolism patients were performed both pulmonary angiography and CT vengraphy. The data were sent to workstation for reconstruction and observation. Postprocessing include multiplanar reconstruction (MPR), curved surface reconstruction (CPR), maximum density projection (MIP)and volume rendering(VR). Results Thirty five patients had pulmonary embolism(PE) and deep venous thrombosis(DVT), 3 had PE, 11 had DVT, and 7 had neither. Conclusion Combined pulmonary angiography and CT vengraphy can well display pulmonary embolism(PE) and/or deep venous thrombosis(DVT), it plays an important role in the diagnosis of pulmonary embolism, suitable for popularization in basic level hospidal.
