Contrast‐enhanced MRI in preoperative assessment of myometrial and cervical invasion, and lymph node metastasis: diagnostic value and error analysis in endometrial carcinoma

摘要: Objective To determine the ability of contrast-enhanced magnetic resonance imaging to predict myometrial invasion, cervical and pelvic lymph node metastasis in endometrial carcinoma analyze factors that lead errors this identification. Design A retrospective study. Setting University general hospital. Population A total 167 women diagnosed with carcinoma. Methods All patients received a preoperative scan. Histopathological findings were used as definitive diagnosis. Main outcome measures The results compared histopathological findings, make accurate assessment difficult by analyzed. Results The sensitivity, specificity, diagnostic accuracy, positive predictive values, negative values 90.9, 91.8, 91.6, 73.2 97.6%, respectively, for identifying deep invasion; 84.2, 96.0, 94.6, 72.7 97.9%, 45.0, 91.2, 85.6, 40.9 92.4%, metastasis. The main causes error myomas, cornual lesions, large tumor size, non-endometrioid type, lower grade. Conclusion Contrast-enhanced has high accuracy low tendency produce false-negative values. Gynecological oncologists should combine data clinical information therapeutic decisions avoid errors.
