This study aims to evaluate the value of quantitative T2-mapping in distinguish rectal tubular adenocarcinoma from non-tubular adenocarcinoma, which can provide rich information and help clinical decision-making. The results showed that the quantitative value of T2mapping of rectal tubular adenocarcinoma was significantly different from that of rectal non-tubular adenocarcinoma. Therefore, quantitative T2 mapping can be used as a non-invasive method for diagnosis rectal tubular adenocarcinoma and non-tubular adenocarcinoma.(AUC:0.824; sensitivity 88.2%;specificity:75%)
