Abstract
At present, MRI is probably the best technique for studying cardiomyopathies, MRI is better than echocardiography in determining the type of cardiac hypertrophy. Myocardial hypertrophy (concentric, asymmetric) can be the result of a variety of disorders. A combination of serial MRI sequences may be extremely helpful in the differential diagnosis.
MRI plays an important role in differentiating between various types of cardiomyopathies using different sequences of MRI combined with contrast enhanced images.
Cardiac MRI has become an important imaging technique for the diagnosis and follow up of cardiomyopathies. cardiac MRI allows an accurate evaluation of myocardial morphology, function, perfusion, and tissue damage in a non invasive way. For these reasons, cardiac MRI has become an important diagnostic tool for cardiomyopathies and is the new reference standard for the assessment of cardiac function.
MRI is of good diagnostic value in differentiating between different types of cardiomyopathies with special emphasis to hypertrophic and restrictive cardiomyopathies where it can precisely detect the structural changes in the ventricular walls and global function changes in the heart so that we can differentiate between both types.
In case of hypertrophic cardiomyopathy MRI is very good in assessing precisely the degree of myocardial hypertrophy where there is marked hypertrophy of the myocardium , segmental variation of interventricular septum and changes affecting cardiac valves especially mitral valve leading to marked mitral regurgitation with subsequent atrial dilatation and finally the global dysfunction of the heart ,with it we can follow up the cases and assess the reponse to treatment and follow up the prognosis.
On the other hand MRI is of high diagnostic value in diagnosing restrictive cardiomyopathy by detecting the presence or absence of myocardial hypertrophy and the damage of both mitral and tricuspid valves leading to marked atrial dilatation with also marked affection of both inferior and superior vena cavae in the form of marked dilatation leading to marked diastolic dysfunction of the heart, with it we can follow up the cases and assess the reponse to treatment and follow up the prognosis.
MRI is also good in diagnosing dilated cardiomyopathy where there is marked dilatation of both right and left ventricles with significant mitral regurgitation leading to marked atrial dilatation leading to subsequent great affection of the function of the heart globally, with it we can follow up the cases and assess the reponse to treatment and follow up the prognosis.
MRI is also very useful in diagnosing arrhythmogenic right ventricular cardiomyopathies especially the help of ECG gated sequences so that we can early diagnose or exclude this type of cardiomyopathy.
