Sorry one more question to go with my post. How reliable are those numbers on an Cardiac MRI?
MRI is very reliable at determining those numbers, but unfortunately for you I don't read MRI's and don't know the accepted normal values. You will need to talk to the doctor that ordered it on this one. Believe it or not most practices aren't routinely ordering cardiac MRI's, in our region it is usually specialized centers or people doing research in that area.
