In this study, we proposed a new 3D segmentation method to segment the arteries and veins from MRA and MRV in the brain, respectively, using a graph-cuts technique and a vessel enhancement filter and then displayed the arteries and veins together in 3D. The MRA and MRV were acquired simultaneously using newly-introduced compatible dual-echo arteriovenography (CODEA). Our proposed method is promising when there is a need to study the morphology of both arteries and veins together in the brain, for example, the characterization and quantification of arteriovenous malformation and brain tumor vascularity.
