Accuracy analysis of CT and MRI in preoperative staging of endometrial carcinoma

Abstract

Objective To investigate the clinical value of computed tamography (CT) and magnetic resonance imaging (MRI) in the preoperative staging of endometrial carcinoma. Methods The clinical data of 98 patients with endometrial cancer hopitalized in Nanshi Hospital from March 2014 to September 2016 were retrospectively analyzed. All patients underwent CT and MRI examination prior to operation. The diagnostic accuracy of preoperative staging of endometrial carcinoma by CT and MRI was analyzed with the pathological results as standard, so as to investigate the consistency of preoperative staging by CT and MRI with pathological diagnosis. Results The accuracy of preoperative staging for endometrial carcinoma diagnosed by CT was 76.53%. The paired chi square test showed that there was no significant difference between the preoperative staging by CT and pathological diagnosis for endometrial carcinoma (χ2=11.667, P=0.070), the two diagnostic methods were in consistence (Kappa=0.611, P=0.000). The accuracy of preoperative staging for endometrial carcinoma by MRI was 87.76%. The paired chi square test showed that there was no significant difference between the preoperative staging by MRI and pathological diagnosis for endometrial carcinoma (χ2=7.333, P=0.291), and preoperative staging by MRI was consistent to pathological results (Kappa=0.799, P=0.000). Theaccuracy of preoperative staging of endometrial carcinoma by MRI was higher than that by CT, and the difference was statistically significant (P<0.05). Conclusions CT and MRI can be used in preoperative staging diagnosis of endometrial carcinoma, but MRI diagnosis is more accurate, and has more clinical value.
