Purpose: To compare the timage quality of computed tomography pulmonary angiography(CTPA) required with contrast medium of 60 ml and 25 ml using 64-slice CT scanner.Materials and Methods: 50 patients suspected pulmonary embolism undergoing computed tomography pulmonary angiography were randomly divided into two groups,the volume of contrast medium was 60 ml,25ml,respectively.Images were evaluated by MPR,MIP and VR.Results: There was no statistical significance in the two groups.The images quality could be diagnostic.Conclusion: CTPA using 25 ml contrast medium can be meet the clinical requirements.
