Future directions
Routine use of CMR have become more common but continues to be limited by factors including wide availability, cost and convenience to patients. Centers with dedicated CMR expertise have improved access. Advances in both scanner technology and new rapid imaging techniques will improved efficiency and decreased scanning time. New techniques may overcome the limitations of breath-holding which can be challenging in DMD patients due to skeletal and respiratory muscle weakness will greatly benefit the DMD population. However, the most important challenge is to demonstrate these surrogate markers of DMD-CM can detect disease progression and changes when given an effective therapy.
