Towards robust high-quality abdominal diffusion weighted imaging: comparison of different reconstruction and signal averaging methods

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
