Cardiac MRI
Cardiac MRI
Cardiac MRI (pronounced: /kɑːrˈdiæk ˈɛmɑːrˈaɪ/), also known as Cardiovascular Magnetic Resonance Imaging, is a medical imaging technology used in the diagnosis and monitoring of heart diseases. The term originates from the Greek words kardia meaning heart, and magnetikos referring to magnetic.
Definition
A Cardiac MRI is a non-invasive imaging method that uses a powerful magnetic field, radio waves, and a computer to produce detailed pictures of the structure and function of the heart. It is used to detect or monitor cardiac disease and to evaluate the heart's anatomy and function in patients with both heart diseases present at birth and heart diseases that develop after birth.
Procedure
The Cardiac MRI procedure involves the patient lying on a table that slides into a large tunnel-shaped scanner. The magnetic field aligns atomic particles in the cells of the body, and radio waves are used to generate cross-sectional images of the heart. These images can be combined to create a detailed 3D image of the heart, allowing for accurate assessment of heart function and structure.
Applications
Cardiac MRI is used in the diagnosis and assessment of a variety of heart conditions, including coronary artery disease, heart failure, heart valve problems, congenital heart defects, cardiomyopathy, and pericarditis. It can also be used to guide the treatment of heart diseases and to monitor the effectiveness of treatments.
