Dictionary learning compressed sensing reconstruction: pilot validation of accelerated echo planar J-resolved spectroscopic imaging in prostate cancer

ConclusionImproved reconstruction of the accelerated 5D EP-JRESI data was observed using the hybrid DLTV. Accelerated acquisition of in vivo 5D data with as low as 8.33% samples (12x) corresponds to a total scan time of 14  min as opposed to a fully sampled scan that needs a total duration of 2.4 h (TR = 1.2 s, 32\({k}_{x}\)×16\({k}_{y}\)×8\({k}_{z}\), 512\({t}_{2}\) and 64\({t}_{1}\)).
