Comparison of the diagnostic efficacy of DWI and DCE-MRI in depth of myometrial invasion, cervical invasion and FIGO staging in patients with endometrial cancer

Abstract

This study aims to compare the diagnostic efficacy of DWI (Diffusion Weighted Imaging) and DCE-MRI (Dynamic Contrast Enhancement-Magnetic Resonance Imaging) in the depth of myometrial invasion, cervical invasion and FIGO (Federation International of Gynecology and Obstetrics) staging in patients with endometrial cancer. 128 patients were selected for preoperative diagnosis with DWI and DCE-MRI techniques. The diagnostic efficacy of the two diagnostic methods on the depth of myometrial invasion, cervical invasion and FIGO staging was compared. Receiver operating characteristic curves were plotted for the two diagnostic methods to further compare the differences between the two diagnostic methods. The accuracy, sensitivity, positive predictive value and negative predictive value of DWI were conspicuously higher than that of DCE-MRI in the diagnosis of depth of myometrial invasion and cervical invasion (p < 0.05). ROC (Receiver Operating Characteristic Curve) analysis demonstrated that the diagnostic effect of DWI was better than that of DCE-MRI in the diagnosis of depth of myometrial invasion and cervical invasion, and the difference in the area under the curve between the two diagnostic methods was statistically significant (p < 0.05). In terms of FIGO staging diagnosis, the accuracy of DWI was 86.72%, which was higher than 65.63% of DCE-MRI (χ 2 = 15.689, p < 0.001). For patients with endometrial cancer, preoperative depth of myometrial invasion, cervical invasion and FIGO staging have critical guiding significance for clinical diagnosis and treatment. Compared with DCE-MRI, DWI has better diagnostic efficacy for depth of myometrial invasion, cervical invasion and FIGO staging, which is worthy of clinical application.
