Conclusion
필기록
Endoleak still remains the major challenge after endovascular aortic aneurysm repair, and it can be misdiagnosed in terms of the location and the types of vessels which are feeding the endoleak. Unlike conventional CT imaging, dynamic time-resolve

Dynamic computed tomography angiography (CTA) imaging provides additional diagnostic value in characterizing aortic endoleaks. This protocol describes a qualitative and quantitative approach using time-attenuation curve analysis to characterize endoleaks. The technique of integrating dynamic CTA imaging with fluoroscopy using 2D-3D image fusion is illustrated for better image guidance during treatment.
