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.
