While a cardiac MRI can produce 3-D images that are far more detailed and precise than fuzzy, 2-D echocardiograms, the procedure is also about five times more expensive. Insurers often resist the use of the technology for screening purposes, but it's usually covered in serious cases. "Generally one can get reimbursed if there's a suspected pathology," says Raymond Stainback, MD, the medical director of noninvasive cardiac imaging at the Texas Heart Institute, in Houston. "Insurers have become much more open to that."
But patients shouldn't start demanding MRI just yet. Echocardiography machines are portable, very quick, and usually quite sufficient to diagnose and monitor a heart condition. "The echocardiogram is still going to be the workhorse," says Dr. Stainback.

I really want to thank Dr Emu for saving my marriage. My wife really treated me badly and left home for almost 3 month this got me sick and confused. Then I told my friend about how my wife has changed towards me then she told me to contact Dr Emu that he will help me bring back my wife and change her back to a good woman. I never believed in all this but I gave it a try. Dr Emu casted a spell of return of love on her, and my wife came back home for forgiveness and today we are happy again. If you are going through any relationship stress or you want back your Ex or Divorce husband you can contact his whatsapp +2347012841542 or email emutemple@gmail.com
