Abstract:
Objective To assess the efficacy of diffusion weighted imaging( DWI) with Magnetic Reso-nance Imaging to predict the T-staging in rectal cancer.Methods One hundred and seven cases confirmed by pathology of rectal adenocarcinoma patients were retrospectively analyzed.T-staging was determined by MRI and DWI combined with MRI.All the patients were underwent surgery within one week after MRI.We compared the results with the pathological T-staging after surgery,and compared the two methods of the preoperative T-stag-ing rectal cancer diagnosis accuracy.Results The accurate rates for T-staging of rectal cancer using MRI was 84.11%(90/107) .There was a correlation between the result of preoperative MRI and postoperative pathological T-staging(kappa=0.652,P<0.001);The accurate rates for T-staging of rectal cancer using combined MRI with DWI was 90.65%(97/107).There was a better correlation between the result of MRI with DWI and postop-erative pathological T-staging(kappa=0.732,P<0.001).Conclusion Compared with the conventional MRI sequences,the accuracy of MRI combined with DWI for diagnosis of T-staging in rectal carcinoma is higher.It can provide a more reasonable treatment.
