Our aim was to investigate the usefulness of multisection dynamic MR imaging using a 3D FLASH technique during breath holding in assessing myometrial invasion by endometrial carcinoma.
Twenty-eight endometrial carcinomas were evaluated with pathologic correlation. Dynamic MR imaging was performed using the 3D FLASH technique during breath holding. We compared accuracy in the assessment of myometrial invasion by endometrial carcinoma between T2-weighted images, contrast-enhanced T1-weighted images, and dynamic MR images.
The accuracy rates in estimating myometrial invasion with T2-weighted images, contrast-enhanced T1-weighted images, and dynamic MR images were 64.3%, 67.8%, and 85.7%, respectively. Statistically significant differences were seen between dynamic MR images and both T2-weighted images and contrast-enhanced T1-weighted images.
Multisection dynamic MR imaging using the 3D FLASH technique during breath holding is useful for the evaluation of myometrial invasion by endometrial carcinoma with polypoid growth or an unclear junctional zone on T2-weighted images.
我们的目的是研究在屏气期间使用三维快速低角度激发（3D FLASH）技术进行多层面动态磁共振成像在评估子宫内膜癌肌层浸润方面的实用性。
对28例子宫内膜癌进行了评估，并与病理结果进行了对照。在屏气期间使用3D FLASH技术进行动态磁共振成像。我们比较了在评估子宫内膜癌肌层浸润方面，T2加权图像、对比增强T1加权图像和动态磁共振图像之间的准确性。
T2加权图像、对比增强T1加权图像和动态磁共振图像评估肌层浸润的准确率分别为64.3%、67.8%和85.7%。动态磁共振图像与T2加权图像和对比增强T1加权图像之间存在统计学显著差异。
在屏气期间使用3D FLASH技术进行多层面动态磁共振成像，对于评估具有息肉样生长或T2加权图像上交界区不清晰的子宫内膜癌的肌层浸润是有用的。
