The purpose was to evaluate the accuracy of multidetector CT (MDCT) on a 16-row CT scanner in local staging of endometrial carcinoma and more specifically in the assessment of the depth of myometrial invasion and presence of cervical infiltration. This prospective study includes 21 women with newly diagnosed endometrial carcinoma. All CT examinations were performed on a 16-row CT scanner, and the protocol included scanning of the abdomen after intravenous administration of iodinated contrast material, during the portal phase, using a detector collimation of 16 x 0.75 mm and a pitch of 1.2. Sagittal, parasagittal and oblique reformatted images were evaluated for the depth of myometrial invasion, whether superficial or deep, and the presence of cervical infiltration. Imaging findings were correlated with the histopathologic results. The sensitivity, specificity and accuracy of MDCT in evaluating myometrial invasion were 100%, 80% and 95%, respectively, and for assessing cervical infiltration were 78%, 83% and 81%, respectively. In conclusion, MDCT on a 16-row CT scanner proved accurate in local staging of endometrial carcinoma.
目的是评估16排CT扫描仪上的多排螺旋CT(MDCT)在子宫内膜癌局部分期中的准确性,更具体地说是评估肌层浸润深度和宫颈浸润情况。这项前瞻性研究纳入了21例新诊断的子宫内膜癌女性患者。所有CT检查均在16排CT扫描仪上进行,扫描方案包括在静脉注射碘化造影剂后,于门静脉期对腹部进行扫描,探测器准直为16×0.75mm,螺距为1.2。对矢状面、旁矢状面和斜位重组图像评估肌层浸润深度(浅或深)以及宫颈浸润情况。将影像学表现与组织病理学结果进行对比。MDCT评估肌层浸润的敏感性、特异性和准确性分别为100%、80%和95%,评估宫颈浸润的敏感性、特异性和准确性分别为78%、83%和81%。总之,16排CT扫描仪上的MDCT在子宫内膜癌局部分期中被证明是准确的。
