Abstract：Objective To investigate the value of magnetic resonance imaging (MRI) in the diagnosis of postoperative local recurrence of rectal cancer.Methods A total of 79 patients with suspected postoperative local recurrence of rectal cancer who admitted to Anshan Central Hospital of Liaoning Province from June 2018 to June 2019 were selected as the research objects.All of the patients were diagnosed with MRI and computed tomography (CT) examinations.The pathological results of surgical biopsy were used as the gold diagnostic standard.The sensitivity,specificity and accuracy of MRI and CT examination in diagnosis of postoperative local recurrence of rectal cancer were compared.Results The pathological results of surgical biopsy showed that there were 48 patients with positive postoperative local recurrence of rectal cancer among the 79 patients with suspected postoperative local recurrence of rectal cancer,and 31 patients were benign changes.There were 49 patients of postoperative local recurrence of rectal cancer diagnosed by MRI examination,45 patients were true positive.There were 46 patients of postoperative local recurrence of rectal cancer diagnosed by CT examination,37 patients were true positive.The sensitivity,specificity and accuracy of MRI examination in the diagnosis of postoperative local recurrence of rectal cancer were 93.75%,87.10%,91.14%,which were higher than 77.08%,70.97%,74.68% of the CT examination,and the differences were statistically significant (P<0.05).Conclusion In the diagnosis of postoperative local recurrence after rectal cancer,the MRI examination has better sensitivity,specificity and accuracy,which can be used as an important means of clinical diagnosis.
