Search for: [Abstract = "s\: The aim of this study was to evaluate the diagnostic performance of two \- dimensional \(2D\) and three \- dimensional \(3D\) ultrasound in the preoperative staging of endometrial cancer and to propose combined transvaginal and transabdominal ultrasound protocol with three\-dimensional modalities applied in order to optimize the diagnosis. Methods\: 87 women diagnosed with endometroid adenocarcinoma were enrolled in this study. GE Healthcare Voluson E6 BT12 system with volumetric endocavitary, transabdominal and linear probes was utilized. Before surgery transvaginal and transabdominal ultrasound scans were performed in each patient to assess local extent of the tumour \(myometrial and cervical involvement\). Following measurements, adopted from the literature or modified by the author, were applied in the myometrial invasion assessment\: maximal endometrial thickness and the antero\- posterior \(AP\) uterine diameter ratio in longitudinal uterine section in 2D and \-3D imaging \(method 1 and 2\), the deepest myometrial invasion distance and uterine wall thickness ratio in longitudinal uterine section in 2D and 3D imaging \(method 3 and 4\), tumour \- free distance from serosa \(TFD\) in 2D and 3D imaging \(method 5 and 6\), tumour and uterine corpus volume ratio in 3D \(method 7\). Deep myometrial invasion was defined if the ratio was more than 50% or the TFD less than 10mm. Basing on the own experi"]
