目的观察和分析子宫三维超声虚拟导航(3D US)用于评估子宫内膜癌浸润子宫肌层深度的诊断价值。方法本研究已获伦理委员会批准,且得到病人口头同意。子宫内膜癌病人在外科手术阶段之前已使用三维超声虚拟导航进行评估,子宫的三维体积用软件分析计算得到。通过分析子宫肌层的侧面、前面、后面以及基底部,虚拟导航就可以从3个正交层面来确定子宫肌层游离肿块到浆膜层的最短距离(TDS), Objective To observe and analyze the diagnostic value of uterine three dimensional ultrasound virtual navigation (3D US) for assessing the depth of myometrial invasion in endometrial carcinoma. Methods This study was approved by the Ethics Committee and was verbally consented to by the patient. Endometrial cancer patients have been evaluated by three-dimensional virtual virtual navigation before the surgical stage, and the three-dimensional volume of the uterus is calculated by software analysis. By analyzing the myometrium’s lateral, anterior, posterior, and basal segments, virtual navigation can determine the shortest distance (TDS) to the serosal layer from the myometrium’s normal mass at three orthogonal levels,
