Influence of Temporal Regularization and Radial Undersampling Factor on Compressed Sensing Reconstruction in Dynamic Contrast Enhanced MRI of the Breast

摘要

ObjectiveTo evaluate the influence of temporal sparsity regularization and radial undersampling on compressed sensing reconstruction of dynamic contrast-enhanced (DCE) MRI, using the iterative Golden-angle RAdial Sparse Parallel (iGRASP) MRI technique in the setting of breast cancer evaluation.
