Reconstructed MBA_T2_slice006 under Cartesian undersampling scheme at 0.35 sampling rate. (a)–(e) Reconstructed images from DLMRI, MRSFLCT based CS MRI, LORAKS, PANO and LSECSMRI, (f)–(j) difference images between fully sampled MR image and images in (a)–(e) with gray scale of [0,0.25], respectively. PSNRs of them are 30.95dB, 30.25dB, 28.33dB, 35.21dB and 3 5 . 8 0dB. TEIs are 0.5806, 0.5872, 0.5218, 0.7513, and 0 . 7 7 6 5. RLNEs are 0.1152, 0.1249, 0.1558, 0.0705 and 0 . 0 6 5 9 separately. And computational time is 62.7+90.5sec, 30.5sec, 711.3sec, 291.2sec and 52.7+514.6sec separately
