Purpose: To develop a diffusion coefficient mapping technique for abdominal imaging with much reduced sensitivity to non-diffusional motions. Methods: Scans were performed with the mixed-TSE pulse sequence using respiratory triggering. PD, T1, and T2 maps were generated and used as input to a Bloembergen-Purcell-Pound model for computing the diffusion coefficient on a pixel-by-pixel basis. Conclusion: A diffusion coefficient mapping technique with much reduced motion artifact vulnerability has been developed. Image quality approaches that of the directly acquired images.
