Coronary vessel wall MRI based on dual inversion
recovery (DIR) is complicated by the need to collect
data during both the period of minimal cardiac motion
and the optimal blood nulling time. We propose a
continuous acquisition scheme throughout an extended
acquisition window after DIR. Combined with golden angle
radial acquisition and k-t sparse SENSE, our framework
enables a fully flexible a posteriori selection of the
optimal imaging time and significantly improves vessel
wall conspicuity with respect to the conventional
acquisition. Our framework alleviates the need of
subject-specific sequence timing and improves the
success rate of coronary vessel wall imaging.
