Herein, we describe a method for implementation of cine DENSE imaging in the abdominal aortic wall. The method uses in house software to post-process and track displacement of intermural pixels and applies a quadrilateral based solution to measure strain. This new method permits the measurement of circumferential heterogeneity of both displacement and strain.
