Abstract: Objective:To explore the value of 64-slice spiral CT angiography in uterine arteriovenous malformation(UAVM).Methods:The image data of 64-slice spiral CT scanning was obtained from two patients with UAVM.Two-dimensional and three-dimensional reformation were performed in all cases including coronal multi planar reconstruction(MPR),maximum intensity projection(MIP),volume rendering(VR).Results:The 64-CTA reconstructed pelvis,common iliac arteries,the internal iliac arteries,the external arteries and their branches was clearly showed.The basic anatomic structure of UAVM was tumor-like dilatation of the vascular sac reconstructed images.The spatial relationship and illustrated feeding arteries and drainage veins could be fully illustrated.Conclusion:64-slice spiral CT angiography can accurately diagnose UAVM.It could provide clear and stereoscopic image data for clinical diagnosis and treatment.
