The clinical significance of synthetic MRI in rectal adenocarcinoma remains unclear. This study aimed to explore the of quantitative parameters derived from SyMRI clinical stage according to “DISTANCE” criteria and differentiation of rectal adenocarcinoma. Our preliminary study demonstrated that quantitative T2 and PD values obtained by SyMRI might be used for noninvasive evaluation of prognostic factors of rectal adenocarcinoma. Furthermore, combining the two quantitative relaxation metrics further improved their diagnostic performance of mrN stage in rectal adenocarcinoma.
