Cardiac MRI: Definition, Clinical Context, and Cardiology Overview
Cardiac MRI is a noninvasive imaging test that uses magnetic fields and radiofrequency pulses to create detailed pictures of the heart. It is a diagnostic test (cardiovascular imaging modality) used to assess cardiac structure, function, blood flow, and tissue characteristics. It is commonly encountered when echocardiography or computed tomography (CT) does not fully answer a clinical question. It is used across cardiology, including cardiomyopathy evaluation, myocarditis workups, congenital heart disease follow-up, and ischemic heart disease assessment.
