Abstract
Cardiomyopathy is classified as ischemic and no-ischemic types, in our study we concern only in non-ischemic form as it is more common in children age group. The non-ischemic cardiomyopathy is further sub divided in to subtypes include DCM, HCM either obstructive or not, LVNC, ARVD, RCM, infiltrative and others depend mainly on morphological criteria. However, they further subdivided in primary or genetic causes and secondary cause’s based on etiology. Non-ischemic cardiomyopathy is a major cause of heart failure in the pediatric age group and must be assessed with echocardiography as a first line imaging modality. However, the cardiac MRI is now considered an important non-invasive imaging modality for assessing the morphologic and functional parameters of heart in cardiomyopathy. Late gadolinium enhancement play an important role in the diagnosis as well as prognosis in cardiomyopathy patients due to its ability in detection of myocardial scarring and fibrosis which can help in diagnosis and differentiation between ischemic and non-ischemic types and narrowing differential diagnosis in non-ischemic form. Moreover using other sequences such as T2WI which can help in differentiation between acute and chronic cardiac injuries and can detect region of inflammation as a guide for further fibrosis and remodeling process. In addition, the use of T2 techniques in quantification of intra myocardial iron deposition in patients with hemochromatosis. Both T2WI & T2 techniques can help in further tissue characterization and accurate diagnosis.
