To emphasis the role of cardiac magnetic resonance compared to echocardiography in evaluating patients with ischemic cardiomyopathy to accurately assess global and regional Left ventricular function which is essential for prognosis and for evaluating therapeutic responses. The studied group included 37 patients already diagnosed as having ischemic cardiomyopathy. All patients were subjected to full history taking and radiological evaluation using a 1.5-T MR system and echocardiography. Comparison was made between echocardiography and cardiac magnetic resonance regarding segmental wall motion by using the 17-segment model of the American Heart Association. Agreement regarding segmental wall motion was assessed by using Cohen’s Kappa statistics. Also ejection fraction measurement by both modalities was compared. Detection of transmural extent of myocardial scar was also performed. Poor agreement between cardiac magnetic resonance and echocardiography regarding segmental wall motion with Cohen’s Kappa is 0.195, P value of
