We developed a method to evaluate thrombus organization as a new parameter in the follow-up of patients afterendovascular repair of abdominal aortic aneurysms. Intra-aneurysmal voxels were classified into three categories by using multispectral MRI-data.. In half of the patients a substantial amount of intra-aneurysmal voxels were hyperintense on the T2w-images. We expect that the size and time course of these hyperintensities provide a new parameter in the follow-up of these patients, using the presented methods we were able to reproducibly measure these volumes.
