Abstract    The development of endovascular techniques depends on the concomitant development of imaging techniques. The ideal imaging method for endovascular aortic repair (EVAR) should provide data for diagnosis, for assessment of the vessel diameters, for characterization of the wall of the aorta and iliac arteries and the aneurysm neck, and for guidance on stent graft deployment, so as to assess the plan of treatment and accurate parameters of stent graft. Angiography alone cannot provide all information necessary for EVAR. Advanced methods, which include rotational angiography , CTA, MRA and intravascular ultrasound, have been playing an important role in endovascular treatment of vascular disease. The combined use of new imaging techniques will further improve the treatment of vascular disease in the future.
