T2-weighted MRI has successfully been used in diagnostic prostate MRI. However, a clinically feasible T2 mapping technique is essential to develop a quantitative MR imaging framework for prostate oncology. This work proposes a novel image acquisition and image reconstruction protocol which exploit the temporal redundancy in the multi-echo fast spin echo imaging sequence used for T2 mapping along with coil sensitivity profile and partial-Fourier MRI to generate T2 maps over whole prostate on the scanner in clinically feasible time of 5min and 55 seconds.
