The aim of this study was to compare the accuracy of transvaginal US (TVUS), CT, and MRI in detecting deep myometrial invasion in endometrial carcinoma.
Twenty-six patients with endometrial carcinoma were evaluated with TVUS, CT, and MRI. The depth of myometrial invasion was estimated in each examination. The invasion depth was categorized into no/superficial and deep and was compared to surgical and pathologic findings.
At pathologic examination, the depth of myometrial invasion was no/superficial in 16 patients and deep in 10. The accuracy/sensitivity/specificity of TVUS, CT, and MRI in detecting deep myometrial invasion were 69/50/81, 61/40/75, and 89%/90%/88%, respectively. The sensitivity and accuracy of MRI in detecting deep myometrial invasion were significantly higher than those of TVUS and CT (p = 0.049 for both sensitivity and accuracy).
We recommend MRI instead of CT or TVUS for the evaluation of the depth of myometrial invasion in endometrial carcinoma.
本研究旨在比较经阴道超声（TVUS）、CT和MRI检测子宫内膜癌肌层浸润深度的准确性。
对26例子宫内膜癌患者进行TVUS、CT和MRI检查。在每次检查中评估肌层浸润深度。将浸润深度分为无/浅肌层浸润和深肌层浸润，并与手术及病理结果进行比较。
病理检查显示，16例患者为无/浅肌层浸润，10例为深肌层浸润。TVUS、CT和MRI检测深肌层浸润的准确性/敏感性/特异性分别为69/50/81、61/40/75和89%/90%/88%。MRI检测深肌层浸润的敏感性和准确性显著高于TVUS和CT（敏感性和准确性的p值均为0.049）。
我们建议采用MRI而非CT或TVUS来评估子宫内膜癌的肌层浸润深度。
