Optimization of b-values in diffusion-weighted imaging for esophageal cancer: Measuring the longitudinal length of gross tumor volume and evaluating chemoradiotherapeutic efficacy

Abstract

MR-DWI b = 800 s/mm2 and b = 1000 s/mm2 are in favor of observing the chemoradiotherapeutic efficacy with time variation and evaluating the chemoradiotherapeutic efficacy, respectively. MR-DWI b = 600 s/mm2 could be used as a supplementary means in measuring the length of ESCC.
