Synopsis

Keywords: Diffusion Reconstruction, Pancreas

Motivation: To prove the feasibility of DWI using echo planar imaging with Compressed SENSE (EPICS-DWI).

Goal(s): Are the images and values obtained by EPICS-DWI reliable?

Approach: Taking both conventional DWI using parallel imaging (PI-DWI) and EPICS-DWI images for the same patient with untreated PDAC within the same examination and compare them.

Results: The ADC value of PDAC did not differ between PI-DWI and EPICS-DWI. EPICS-DWI can improve the qualitative overall image quality and PDAC-to-pancreas CNR compared to PI-DWI. The qualitative PDAC conspicuity was comparable between PI-DWI and EPICS-DWI.

Impact: EPICS could improve image quality of high-b value DWI images without any worries about significant changing of ADC values of PDAC.
