T1 mapping of the myocardium shows great promise for
quantitative characterization of myocardial tissue. The
partial separability (PS) model has previously been
shown to be effective for reducing the data acquisition
requirements of static parameter mapping; here we extend
the model to accelerate variable-flip-angle dynamic 3D
T1 mapping using a time-varying subspace (or
tensor-product subspace). We have successfully applied
the proposed method to significantly accelerate
variable-flip-angle dynamic 3D T1 mapping for diagnosis
of ischemic reperfusion injury in rats.
