Quantitative T2 Estimation Using Radial Turbo Spin Echo Imaging

There has been increased interest in the quantitative characterization of tissues based on T2 in abdominal imaging. Techniques based on spin-echo or turbo spin-echo sequences are time consuming because they require multiple acquisitions for obtaining an adequate number of TE images for accurate T2 mapping. Radial turbo spin echo (RADTSE) based methods have been shown to generate accurate T2 maps from a single acquisition using highly undersampled data. In this work, we present details of the RADTSE technique, summarizing developments related to the design of pulse sequence and reconstruction algorithms. Results from phantom and in vivo imaging experiments are also presented.
