Cardiac Magnetic Resonance Imaging (CMR), also known as Cardiac MRI, is a non-invasive medical imaging technique that uses powerful magnets, radio waves, and computer technology to create detailed images of the heart and its structures. It provides comprehensive information about the heart’s anatomy, function, and blood flow, allowing healthcare professionals to assess various cardiac conditions and plan appropriate treatments.
During a cardiac MRI, the patient lies on a table that is slowly moved into the MRI machine, which creates a strong magnetic field. Radio waves are then emitted, causing the hydrogen atoms in the body to resonate. These atoms emit signals that are detected by the machine's sensors and used to generate highly detailed images of the heart.
Cardiac MRI is particularly useful in evaluating and diagnosing various cardiovascular diseases, including coronary artery disease, myocardial infarction, congenital heart defects, valvular heart disease, cardiomyopathy, arrhythmias, and pericardial diseases. It can provide information about the size, structure, function, blood flow, and metabolism of the heart, allowing for accurate diagnosis and assessment of treatment effectiveness.
This imaging technique is generally safe, but precautions are necessary for patients who have certain metallic implants, as the strong magnetic field can disrupt or heat these objects. Cardiac MRI is typically performed by experienced radiologists or cardiologists who specialize in cardiac imaging, and the results are interpreted by these medical professionals to guide patient care.
