磁共振成像诊断子宫内膜癌肌层浸润深度的探讨

The value of magnetic resonance imaging to evaluate myometrial invasion of endometrial carcinoma

目的:探讨磁共振成像穴magneticresonanceimaging熏MRI雪诊断子宫内膜癌肌层浸润程度的准确性及其临床应用价值。方法:对51例经手术病理证实为临床Ⅰ期的子宫内膜癌患者术前行MRI检查,判断其肌层浸润程度熏并与术后病理结果进行对照分析。结果:51例患者术前MRI均能做出准确诊断,其判断子宫内膜癌肌层浸润的准确率为86.27%穴44/51雪,浅肌层浸润的准确率88.46%穴23/26雪,深肌层浸润的准确率88.23%穴15/17雪,动态增强MRI的准确率为90.5%穴19/21雪。结论:MRI能准确地诊断子宫内膜癌并判断肌层浸润深度,动态增强MRI尤为准确,是术前判断肌层浸润程度的有效途径。

Objective： To evaluate the application of magnetic resonance imaging （MRI） in detecting the depth of myometrial invasion in patients with endometrial carcinoma. Method： MRI was performed in 51 patients with endometrial carcinoma to diagnose the depth of myometrial invasion. Results： MRI made right diagnosis in all 51 patients with endometrial carcinoma before operation. The total accurate rate of MRI in detecting the depth of myometrial invasion was 86.27% （44/51）. The accurate rate in detecting superficial and deep myometrial invasion was 88.46%（23/26） and 88.23%（15/17） respectively. The accurate rate of dynamic gadolinium-enhanced MR imaging was 90.5% （19/21）. Conclusion： MRI, especially dynamic MRI, plays an important role in the diagnosis of endometrial carcinoma and in judging the depth of myometrial invasion, and should be an useful way in preoperative diagnosis of endometrial carcinoma.
