| Outline of Final Research Achievements |
There were 36 patients of endoleak after endovascular abdominal aortic aneurysm repair or thoracic endovascular aortic repair for 2 years. Among them, 12 patients underwent contrast enhanced 4-dimensional CT (4D-CT) using by 320 MDCT. Type 2 endoleak was caused by the lumber artery, the inferior mesenteric artery, the median sacral artery, and 4D-CT rendering of these vessels was relatively good. In addition, we could diagnose 2 cases of type 3 and 1 case of type 1a which we considered type 2 endoleak befor 4D-CT. We consider that 4D-CT makes it possible to classify endoleaks. As for image processing, we consider that the multi-planar reconstruction is better than maximum intensity projection or volume rendering.
