Reduced acquisition time of female pelvis diffusion weighted imaging (DWI) using LIPO-only (LION) DWI

We hypothesized that LIPO-only (LION) DWI might be one of the best solutions to reduce the acquisition time of female pelvis DWI if it is further optimized to increase the robustness of fat suppression. We compared the image quality of DWI in the female pelvis between the conventional method (SPAIR-DWI) and the proposed method (LION-DWI) to investigate their clinical usefulness. LION-DWI showed correct signal decay because fat suppression pre-pulse was not applied. LION-DWI can reduce acquisition time of the pelvis DWI while maintaining the SNR and sufficient image contrast.
