We used a novel DCE-MRI sequence [Golden-angle RAdial
Sparse Parallel (GRASP)] that employees compressed
sensing and continuous radial acquisition to
retrospectively reconstruct prostate DCE-MRI data
obtained after a single contrast injection at temporal
resolutions varying between approximately 1 and 10
seconds. The temporal resolution did not impact
diagnostic performance of quantitative DCE metrics for
tumor detection.
