[Abstract] Objective To investigate the diagnostic value of preoperative MRI in the depth of muscular invasion and cervical invasion of endometrial carcinoma.Meterials and Methods: One hundred and sixty two cases of endometrial carcinoma confirmed by operation and pathology were retrospectively included, aged 25 to 72 years old, median age 53-year-old. The depth of myometrial invasion and cervical involvement were evaluated by MR multisequence. And using pathological results as the gold standard, the sensitivity, specificity and accuracy of MRI diagnosis were calculated by diagnostic test formula. The Kappa test was used to evaluate the consistency between preoperative MRI results and surgical pathology results.Results There were 162 cases of endometrial carcinoma confirmed by surgical pathology, including 137 cases of stage Ⅰ and 25 cases of stage Ⅱ. The sensitivity, specificity and accuracy of superficial myometrial infiltration were 94.7%, 93.3% and 94.4%, respectively. The sensitivity, specificity and accuracy of the diagnosis of deep myometrial invasion were 93.3%, 94.7% and 94.4%, respectively. The preoperative MRI evaluation of myometrial invasion was consistent with the operative pathological results (k=0.83). The sensitivity, specificity and accuracy of cervical invasion diagnosis were 48.0%, 94.2% and 87.0%, respectively. Preoperative MRI evaluation of cervical invasion had moderate consistency with surgical pathology results (k=0.46).Conclusions Preoperative MRI plays an important role in the diagnosis of myometrium invasion and cervical invasion of early endometrial carcinoma, and has a certain guiding role in the development of personalized treatment plan.
