One advantage of a Cardiac MRI is that there is no ionising radiation involved in the procedure and the magnetic field is not harmful. The test is also pain-free but may be uncomfortable as you need to lie down on the MRI machine table for about an hour.
As there is no risk of radiation, an MRI can also be done for pregnant patients. However, do inform your doctor as the contrast, rather than the MRI itself could also be a risk for the baby. Additionally, some patients may be allergic to the contrast.
Prior to the test, it is important to let your doctor know of any prior health problems you may have had, surgeries you’ve done and if you are pregnant. You may also want to let your cardiologist know if you suffer from claustrophobia or anxiety.
