目的评价磁共振扩散加权成像(DWI)在子宫内膜癌术前分期中的价值及与病理结果的相关性。方法回顾性分析30例经手术病理证实的子宫内膜癌患者MR检查资料,将DWI检查结果与病理结果进行对照,比较子宫内膜癌不同病理类型、不同分化程度的ADC值是否有统计学差异。结果 DWI对子宫内膜癌术前分期的准确性为83.3%。子宫内膜癌的ADC值为(0.856±0.080)×10-3mm2/s,不同病理类型之间无统计学差异(P>0.05),不同分化程度组间有统计学差异(P<0.01)。结论 DWI在子宫内膜癌术前分期中具有较高的准确性,能够显示病变的浸润深度;通过ADC值的测量,能够初步反映肿瘤的恶性程度。
Objective To evaluate the value of diffusion weighted imaging (DWI) in preoperative staging of endometrial carcinoma and its correlation with pathological findings. Methods A retrospective analysis of 30 cases of pathologically confirmed endometrial cancer patients MR examination data, the results of DWI examination and pathological results were compared, the different pathological types of endometrial cancer, different degrees of differentiation of the ADC values are statistically significant . Results The accuracy of DWI in preoperative staging of endometrial carcinoma was 83.3%. The ADC value of endometrial carcinoma was (0.856 ± 0.080) × 10-3mm2 / s, and there was no significant difference between different pathological types (P> 0.05). There were significant differences among different differentiation groups (P <0.01). Conclusion DWI has a high accuracy in the preoperative staging of endometrial cancer, which can show the depth of invasion of the lesion. The ADC value can reflect the degree of malignancy of the tumor.
