Abstract
Objective To explore the application of magnetic resonance diffusion weighted imaging signal features in the invasion of the serosal layer in rectal cancer.Methods A retrospective analysis was conducted on the magnetic resonance imaging data of 53 cases of rectal cancer.Patients were divided into T2 and T3 groups based on postoperative pathological sections.Evaluate the correlation between the relative signal intensity(rSI)ratio of rectal tumors,blurry boundaries,poorly defined margins,and surface diffusion coefficient with in-vasion of the rectal serosal layer.Results There were 33 cases in the T2 phase group and 20 cases in the T3 phase group.There were sta-tistically significant differences between the two groups in terms of rSI of rectal tumors and poorly defined margins of rectal tumors(P<0.05).The analysis results of the receiver operating characteristic curves showed that the sensitivity and specificity of rSI and combined diagnosis(rSI+poorly defined margins)in diagnosing rectal cancer serosal invasion were 100%and 57.6%,90%and 66.7%,respectively,and the area under curve was 0.826 and 0.903,respectively.Conclusion There is a correlation between rSI combined with poorly defi ned margins and invasion of the serosal layer in rectal cancer,which has certain reference value for clinical evaluation of patients'condi-tion and guidance of clinical treatment.关键词
