Stimulated echo diffusion weighted imaging of the liver at 3T

Power Pitch Session - Body: no. 0845Diffusion-weighted imaging (DWI) has been increasingly used in clinical applications due to its sensitivity to microscopic motion in biologic tissue. However, the DW signal depends on not only b-value but also the diffusion time due to restricted diffusion phenomenon. This work proposed an optimized stimulated-echo (STE) DWI method and aimed to investigate the dependence of diffusion measurement on diffusion time in healthy human liver. The results show that restricted diffusion behavior is observed in human liver at 3T, which demonstrates the effect of both b-value and diffusion time on liver DWI quantification
