This paper presents Centerline Trajectory Mapping (CTM) method as a quantitative tool for characterization of focal and global wall motion abnormalities using long axis views of the left ventricle. Evaluation of CTM with myocardial delayed enhancement imaging and echocardiography with great consistency in wall motion abnormality detection. The proposed method does not add any extra scans to existing clinical cardiac MR routine and can be utilized in retrospective studies.
