Why aren't we measuring T2* more often?

I have just returned from a Latin American Conference on Iron Overload. It was staggering to note that so few sites in Latin America are performing T2* studies for studying iron overload of the liver and heart. There are a substantial number of patients with MDS, thalassemia, primary hemocromatosis and other diseases where the hematogists really want the information provided by CMR. I have heard from many hematologists that they don’t order the exam because nobody does it in their respective country. We estimate that this would increase the volume of patients by at least 1-5 patients/monthly. Considering that the average CMR site does 20-50 exams per month and you can do the math of what this loss of patients represents.
