Abstract:
Objective To evaluate the application of MSCT 3D reconstruction technology without contrast on pulmonary arterio-venous malformation(PAVM).Methods The clinical and imaging data of 12 cases with PAVM confirmed by DSA were analyzed ret-rospectively.The plain scan with 16 slice spiral CT scanner performed pulmonary 3D reconstruction at post-processing work station by methods of MPR,MIP and VR.Results All cases could be diagnosed accurately,and images could clearly show the spatial struc-tures and its relations of the feeding arteries,draining vein and aneurysmal sac.Conclusion MSCT post-processing technique of PAVM without contrast is able to make a precise diagnosis,and to show the configuration of PAVM,which does not need contrast medium and acquirelow radiation dose.
