To reduce image distortion in MR diffusion imaging using an accelerated multi-shot method. ⋯ An accelerated motion-corrected diffusion imaging method was introduced that achieves good image quality at relatively high acceleration factors.

To quantitatively evaluate lung perfusion using Fourier decomposition perfusion MRI. The Fourier decomposition (FD) method is a noninvasive method for assessing ventilation- and perfusion-related information in the lungs, where the perfusion maps in particular have shown promise for clinical use. However, the perfusion maps are nonquantitative and dimensionless, making follow-ups and direct comparisons between patients difficult. We present an approach to obtain physically meaningful and quantifiable perfusion maps using the FD method. ⋯ Quantitative lung perfusion can be obtained using the Fourier Decomposition method combined with a small amount of postprocessing.
