A new 3D diffusion imaging technique has been presented by using Steady-State Free Precession (SSFP) DWI and 3D rotation spirals (3DRS). The novel acquisition scheme offers very high SNR efficiency and low sensitivity to motion artifacts. In addition, the 0th order phase errors can be extracted and corrected with 3DRS. Experimental results have shown that high quality DWI and DTI whole brain volumes can be rapidly acquired with high SNR.
