Enhanced Fat Suppression Effect by Integrating STIR DWI with PROSET

Motivation: In this study, the motivation was to improve fat signal suppression in Diffusion-weighted Whole Body Imaging with Background Body Signal Suppression (DWIBS). Goal(s): The specific goals were to evaluate the fat suppression effect of the Principle of Selective Excitation Technique (PROSET) in combination with STIR DWI (PROSET-STIR DWI) compared to conventional methods. Approach: The approach involved scanning healthy volunteers using PROSET-STIR DWI, STIR DWI and SPAIR DWI. Results: The results revealed that PROSET-STIR DWI achieved superior fat suppression for Methylene signals compared to conventional methods. Overall, PROSET-STIR DWI demonstrated enhanced fat suppression, highlighting its potential in clinical applications. Impact: The PROSET-STIR DWI technique demonstrates superior fat suppression compared to conventional methods, with notable differences in Methylene fat signals. This advance can benefit medical imaging, potentially improving cancer detection and diagnostic accuracy.
