Accelerated non-Cartesian parallel imaging plays a vital role to reduce data acquisition time in the MR imaging; however the resultant images may contain aliasing artifacts. In this work, the application of ESPIRiT with GROG is proposed to get good reconstruction results from highly under-sampled radial data. The proposed method is tested on 3T short–axis cardiac radial data at different acceleration factors (AF=4, 6 and 9) and compared with pseudo-Cartesian GRAPPA. The results show that the proposed method offers significant improved (e.g. 81% improvement in term of artifact power at AF=4) reconstruction results as compared to conventional pseudo-Cartesian GRAPPA.
