磁共振成像在子宫颈癌术前分期中的诊断价值

目的：探讨在子宫颈癌术前分期中应用磁共振成像的诊断价值。方法2010年3月~2013年3月在我院经病理证实为宫颈癌的35例手术患者行MRI检测。结果MRI与宫颈癌于T2WI上呈高信号表达。对宫颈癌疾病整体检出，MRI灵敏度85.71％（30/35）。而对于Ⅰb以上的灵敏度为100％（35/35）。临床分期敏度仅为74.29％（26/35），对于Ⅰb以上的灵敏度为65.71％（23/35）。与MRI比较，差异有统计学意义（P＜0.05）。结论MRI对术前宫颈癌分期明显优于临床分期，可作为宫颈癌术前常规的影像学检查方法。

Diagnostic value of magnetic resonance imaging in preoperative staging of cervical cancer

Objective To evaluate the diagnostic value of magnetic resonance imaging in the preoperative staging of cervical cancer. Methods Thirty-five patients pathologically confirmed with cervical cancer in our hospital from March 2010 to March 2013 received MRI detection. Results MRI and cervical cancer presented high signal expression on T2WI. For the overall detection of cervical cancer related diseases, the MRI sensitivity was 85.71% （30/35）. The sensitivity forⅠb above was 100%（35/35）. The sensitivity of clinical staging was only 74.29%（26/35） and the sensitivity of Ⅰb above was 65.71% （23/35）. Compared with MRI, there existed statistically significant difference （P〈0.05）. Conclusion MRI is obviously better than clinical staging for preoperative cervical cancer and can be used as the routine imaging examination method for cervical cancer.
