Abstract

This paper summarizes the clinical value of spiral CT and MRI in preoperative staging of rectal cancer. From January 2018 to April 2019, 100 patients with rectal cancer were selected as cases for study and analysis. All patients underwent CT and MRI examinations. The results of CT and MRI imaging, circumferential margin and lymph node diagnosis were judged by pathological diagnosis as the golden standard. With pathological diagnosis as the gold standard, the coincidence rate of MRI diagnosis was significantly higher than that of CT diagnosis, with significant difference in staging data and significant comparison between groups (P < 0.05); in predicting circumferential margin and pathological results of the two diagnostic methods, the predictive results of MRI were more ideal, the diagnostic effect was prominent, and the data difference was significant. The comparison results were significant (P < 0.05); the accuracy rate of MRI diagnosis was higher than that of spiral CT to a certain extent, but the difference of data was not obvious, and the comparison results were meaningless (P > 0.05). Both spiral CT and MRI scan have certain clinical value in the preoperative diagnosis of rectal cancer. Compared with CT, MRI has higher clinical value in preoperative staging of rectal cancer. It is necessary to make a comprehensive diagnosis according to the needs of patients. Combined with two diagnostic methods, it provides a reliable basis for surgical treatment and is worthy of promotion in the clinic.
