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.
