Predictability of myometrial, lower uterine segment and cervical invasion with 3D transvaginal ultrasonography and magnetic resonance imaging in endometrial cancer patients: a prospective cohort study

Abstract Aims: The objective of this study is to identify the diagnostic performance of three-dimensional transvaginal ultrasonography (3D-US) and magnetic resonance imaging (MRI) in detecting myometrial, lower uterine segment and/or cervical invasion in endometrial cancer patients. Materials and methods Forty patients diagnosed with endometrial cancer with endometrial biopsy (dilatation and curettage) between 2013-2016, in Dokuz Eylul University, Faculty of Medicine, Department of Obstetrics and Gynecology, were included in this study. First preoperative peritoneal washings were collected for cytological evaluation. Statistical Analysis Sensitivity, specificity, negative and positive predictive values and accuracies were calculated for 3DUS, MRI and combination of both techniques in detecting deep myometrial, lower uterine segment and cervical invasion in endometrial cancer.
