The application value of multi slice spiral CT angiography in evaluating pulmonary artery embolism

Objective To explore the application value of multi slice spiral CT angiography in evaluating pulmonary artery embolism.Methods Data of 11 patients with pulmonary artery embolism were retrospectively analyzed,the contrast-enhanced SCT scans of the pulmonary arteries were performed.MPR,MIP and VR were performed simultaneously.Results The CT value of enhanced pulmonary artery was obviously higher than the thrombus,the position and morphology of embolus in pulmonary artery were clearly displayed in cross section CT pictures with MPR,CPR,MIP and VR.Conclusion Multi slice CT angiography can clearly show the position and morphology of embolus in pulmonary artery,which has obvious technique advantage and higher value in the diagnosis of pulmonary artery embolism.
