Cardiac magnetic
resonance imaging (cMRI) is a noninvasive test that provides a highly detailed
assessment of the structure and function of the heart and its vessels. cMRI
does not rely on X-rays, but on magnetic fields and radio waves.
What Happens During a Cardiac MRI?
The patient is
placed in a large “doughnut” which contains a powerful magnet; a radio wave is
transmitted by a light antenna (coil) placed on the chest. The coil receives
back the radio waves as modified by the magnet and a complex computer program
transforms the radio wave signal into a 2D or 3D image.
Who Can Receive a Cardiac MRI?
Most patients can
have a cMRI study, unless their body contains certain metallic implants that
could be displaced by the magnet. The test can take up to 1 hour and you will
be asked to hold your breath for relatively short periods of time during the
scan.
Benefits of Cardiac MRI
cMRI provides vivid,
highly detailed images and movies of your heart that can diagnose very complex
congenital or acquired structural disease defects. In addition, cMRI represents
the gold standard for evaluation of the heart pumping function and of heart
muscle scars developed after a heart attack, helping the cardiologist to decide
on future treatment strategies.
