ABSTRACT

Objective To explore the value of 64-slice spiral CT angiography in diagnosis of pulmonary arteriovenous fistulas(PAVF).Methods 12 patients with suspect PAVF were performed by enhanced scan with 64-SliceCT.Two-dimensional and three-dimensional reformation were performed in all cases including coronal multiplanar reconstruction(MPR),maximum intensity projection(MIP),volume rendering(VR).Resnlts 12 cases were diagnosed as PAVF by 64-SliceCT angiography.Single PAVF in 7 cases,Multi-PAVF in 5cases.We found 20 lesions in 12 patients,Except direct multi-pulmonary arteriovenous fistulas in the area of near the heart in one case.Conclusion 64-slice spiral CT angiography is a useful and noninvasive means to identify PAVF and is also useful for therapeutic planning and postoperative follow-up.
