To optimize the use of radial spin-echo sequences, SNR characterization for relevant T1 and T2 ranges is required. In this work, we studied the interplay between the number of excitations (Nexc) and the turbo factor (NTF - number of echoes within each TR) on the SNR of images acquired using the RAISE (RAdIal Spin Echo) sequence. SNR was evaluated for phantom and in-vivo images. Phantom analysis focused on SNR per T1 and T2 ranges appropriate for known gray and white matter relaxation times. Selected parameter sets were later used for in vivo scans for qualitative evaluation.
