Introduction
Cardiac MRI provides comprehensive assessment of cardiac structure function perfusion and tissue characterization. Cine imaging perfusion late gadolinium enhancement and T1 T2 mapping are core components of cardiac MRI protocols. Quantitative mapping supports diagnosis of myocarditis cardiomyopathy and infiltrative disease.
Acquisition and Gating
ECG gating and breath hold strategies are essential to minimize motion and obtain diagnostic cine and mapping images. Use of contrast agents and first pass perfusion sequences evaluates ischemia and microvascular disease. Mapping sequences require standardized acquisition and reference values for interpretation.
Clinical Applications
Cardiac MRI is the reference standard for ventricular volumes ejection fraction and myocardial viability assessment. It detects myocarditis amyloidosis and iron overload and guides management of cardiomyopathies. Serial imaging monitors therapy response and device related complications.
Quality and Safety
Heart rate variability arrhythmia and implanted devices can complicate acquisition and require tailored protocols. Gadolinium use requires assessment of renal function and consideration of cumulative exposure. Collaboration with cardiology and physics teams ensures reproducible quantitative results.
