The purpose of this study is to investigate the feasibility of applying CS theory to breast DCE-MRI to improve the temporal resolution while faithfully reconstructing uptake curves. In the preliminary experiment, DCE images were reconstructed using Reference Image based Compressed Sensing technique (RICS). The uptake curve reconstruction experiment shows a high correlation between uptake curves reconstructed from fully sampled data by Fourier transform and from undersampled data by RICS, indicating high similarity between them. In conclusion, our preliminary results demonstrate the feasibility of RICS for improving temporal resolution and faithfully reconstructing uptake curves of DCE-MRI.
