GRASP-Pro reconstruction in DCE dataset 4. (a) the z projection profiles show that the subject had irregular breathing during data acquisition. (b) GRASP-Pro was able to reconstructed good images in different contrast phases with a temporal resolution of 0.78 seconds/3D volume. (c) Comparison of low-temporal-resolution GRASP reconstruction (15 seconds/3D volume) and motion-weighted GRASP reconstruction (15 seconds/3D volume) with high-temporal-resolution GRASP-Pro reconstruction (0.78 seconds/3D volume) in a venous contrast phase. GRASP-Pro was able to recover small details (small vessels) that are blurred in GRASP and motion-weighted GRASP (likely due to motion and irregular breathing from low-temporal-resolution reconstruction).
