Iron accumulation is a side effect from regular blood transfusions, which are a common treatment for diseases like hemochromatosis and sickle cell disease. T2* mapping can be a useful tool in therapy planning as it allows for monitoring of the iron accumulation in the heart. Multi-echo-GRASP offers a method of T2* mapping for all phases of the cardiac cycle. The acquisition can be performed in free breathing which is beneficial for patients with an impaired cardiac and/or respiratory capacity.
