The Role of Cardiac Magnetic Resonance Imaging in Non-Ischemic Cardiomyopathies

Background: Nonischemic Cardiomyopathies including Myocarditis and Primary Cardiomyopathies as hypertrophic CMP, dilated CMP, restrictive CMP, noncompation CMP. Echocardiography is the intial evaluative method for CMP diagnosis, but it is limited by poor acoustic windows. Cardiac magnetic resonance imaging allows accurate assessment of myocardial anatomy, function and tissue characterization. End point of study: To review the ability of cardiac MRI in the diagnosis of nonischemic cardiomyopathies. Result: 185 patients with nonischemic cardiomyopathies of 243 patients underwent cardiac MRI with 1,5 Tesla GE Explorer at Medic HCMC, since October 2020 to April 2023. In which, 88% of primary CMP and 12% of Myocarditid were notified. Patients had CMR using the 1.5 Tesla GE Explorer and CVI 42 version 5.13.10, with the following protocol: Axial FIESTA, SA cine, 4C and 2C cine, T1 mapping with MOLLI, Triple IR FSE T2, myocardial perfusion imaging TI, LGE-MRI. Conclusion: Cardiac MRI has been useful imaging modality for assessment nonischemic cardiomyopathies with the high accuracy. Cardiac MRI is not only the establishing diagnosis but also prognosis.
