To investigate the efficacy of thin-section oblique axial magnetic resonance (MR) images in evaluating cervical invasion by endometrial carcinoma.
Sixty-seven patients with endometrial carcinoma were evaluated with pathologic correlation. We compared the accuracy in the assessment of cervical invasion by endometrial carcinoma between parasagittal MR images and thin-section oblique axial MR images by using T2-weighted and contrast-enhanced T1-weighted pulse sequences.
Cervical invasion by endometrial carcinoma was confirmed by pathologic examination. Cervical invasion was seen in 16 patients. The accuracy rates of parasagittal T2-weighted images, thin-section oblique axial T2-weighted images, parasagittal contrast-enhanced T1-weighted images, and thin-section oblique axial contrast-enhanced T1-weighted images were 74.7%, 89.5%, 82.0%, and 95.5%, respectively. Statistically significant differences were seen between parasagittal T2-weighted images and thin-section oblique axial T2-weighted images (p = 0.002) and between parasagittal contrast-enhanced T1-weighted images and thin-section oblique axial contrast-enhanced T1-weighted images (p = 0.003).
Thin-section oblique axial MR images are considered to be useful for the assessment of cervical invasion by endometrial carcinoma.
探讨薄层斜轴位磁共振(MR)图像在评估子宫内膜癌宫颈浸润方面的效能。
对67例子宫内膜癌患者进行评估,并与病理结果进行对照。我们采用T2加权和对比增强T1加权脉冲序列,比较矢状位MR图像和薄层斜轴位MR图像在评估子宫内膜癌宫颈浸润方面的准确性。
经病理检查证实存在子宫内膜癌宫颈浸润。16例患者出现宫颈浸润。矢状位T2加权图像、薄层斜轴位T2加权图像、矢状位对比增强T1加权图像和薄层斜轴位对比增强T1加权图像的准确率分别为74.7%、89.5%、82.0%和95.5%。矢状位T2加权图像与薄层斜轴位T2加权图像之间(p = 0.002)以及矢状位对比增强T1加权图像与薄层斜轴位对比增强T1加权图像之间(p = 0.003)存在统计学显著差异。
薄层斜轴位MR图像被认为对评估子宫内膜癌宫颈浸润有用。
