A major challenge in applying MRF to myocardial tissue
characterization is that respiratory and cardiac motion
can introduce blurring in parameter maps or lead to
failed pattern recognition. A 2D MRF acquisition is
presented that employs a single breath hold and ECG
triggering to simultaneously map T1, T2, and M0 within
24 heartbeats. Because the exact timing for the
experiment differs for each scan due to slight
differences in cardiac rhythm, scan-specific
dictionaries are used for pattern matching. Six healthy
volunteers were scanned at 3T, and myocardial relaxation
parameters were in good agreement with literature
values.
