Abstract: Objective:To evaluate the clinical value of 3.0 MRI imaging in evaluating the circumferential margin of rectal cancer.Methods:From March 2016 to May 2018, 105 cases of rectal cancer with definite pathology in Shaoxing People's Hospital were evaluated by preoperative MRI and post-operative pathology.The accuracy, sensitivity, specificity, positive predictive value and negative predictive value were obtained.Results:The accuracy, sensitivity, specificity, positive predictive value and negative predictive value were 87.62%(92/105), 50.00%(1/2), 88.35%(91/103), 7.69%(1/13)and 98.91%(91/92), respectively.Conclusion:The accuracy of MRI in evaluating CRM is higher, the specificity and negative predictive value are higher, while the sensitivity and positive predictive value are lower.The reason is related to enlarging the resection scope during operation.Whether it will affect the prognosis of patients needs further follow-up results.
