Dynamic Contrast Enhanced (DCE) MRI has become an indispensable tool for tumor diagnostics. Any improvement in the achievable temporal resolution can be very useful, due to the trade-off between spatial and temporal resolution that exists in the current imaging schemes. This work reports a novel strategy of combining UNFOLD with time resolved imaging to effect acceleration factors of 6 and higher, thereby pushing the capabilities of DCE-MRI further. A new, computationally efficient, sinc-interpolation based reconstruction strategy has also been proposed. Tests conducted on real and simulated data validate the accuracy and increase in temporal resolution obtained using this new acquisition-reconstruction technique.
