The role of cardiovascular magnetic resonance in evaluating myocardial perfusion and scar tissue: An Institutional Study.

Introduction: Cardiovascular Magnetic Resonance (CMR) has become an essential non-invasive imaging modality in the diagnosis and management of various cardiac conditions. Its ability to provide detailed assessments of myocardial perfusion and scar tissue without ionizing radiation offers distinct advantages over other imaging techniques. Aim is to evaluate the role of Cardiovascular Magnetic Resonance (CMR) in assessing myocardial perfusion and scar tissue and to investigate the correlation of CMR findings with clinical parameters and outcomes, including angina symptoms, history of myocardial infarction, and revascularization procedures. Materials and Methods: This prospective observational study was conducted with a sample size of 75 patients who had clinical indications for CMR. The study included adult’s aged 18 years and older, excluding those with contraindications to MRI or severe renal impairment. CMR imaging was performed using a 1.5 Tesla MRI scanner, incorporating cine imaging, stress and rest perfusion imaging, late gadolinium enhancement (LGE), and T1 and T2 mapping. Results: The study found that 30% of participants exhibited myocardial perfusion defects, with a mean scar burden of 15% across the study cohort. Participants with angina symptoms, a history of myocardial infarction, or those who underwent revascularization procedures had higher scar burdens and lower left ventricular ejection fractions (LVEF). Significant correlations were observed between CMR findings and clinical outcomes, with participants who had a history of myocardial infarction showing the highest scar burden (mean 30%) and lowest LVEF (mean 45%). Conclusion: CMR is a valuable tool for evaluating myocardial perfusion and scar tissue, with significant correlations to clinical outcomes. This study confirms the importance of CMR in the management of cardiovascular diseases and suggests that further research and advancements are necessary to enhance its accessibility and utility in diverse healthcare settings.
