Synopsis

Keywords: Liver, Diffusion/other diffusion imaging techniques

Motivation: One of the limitations of current abdominal DWI is to obtain robust image quality, especially for SNR and image sharpness.

Goal(s): Our goal was to compare a combination of different reconstruction and averaging methods for abdominal DWI and to explore which combination is the best.

Approach: We compared five combinations of reconstruction and averaging methods and image quality was evaluated by visual evaluation and quantitative evaluation.

Results: We demonstrated the image quality of abdominal DWI could be improved by using either Ssh-DWI or CS-Complex averaging with comparable ADC values to conventional methods.

Impact: For the next step, a combination of CS reconstruction and Ssh-IRIS would be desirable for further improvement of image quality
