A reconstruction method was presented by Pruessmann et al. for Sensitivity Encoding (SENSE) with arbitrary k-space trajectory. This method requires gridding step which converts the coordinates from arbitrary grid to Cartesian grid. Therefore, it suffers from the gridding interpolation error in the reconstructed image. In this study, we proposed a reconstruction algorithm for parallel imaging with radial k-space trajectory. The presented method does not require gridding step and can reconstruct the images using only magnitude informationof the projection data which is obtained after the Fourier transform along the radial direction.
