| 摘 要：［目的］ 探讨MRI扫描在宫颈癌术前诊断、分期中的应用价值。［方法］ 回顾性分析67例宫颈癌患者的术前MRI平扫、动态增强表现，分析肿块影像特点，邻近组织受侵情况及远处脏器转移情况，对MRI分期、临床分期及术后病理分期进行对照。［结果］ 宫颈癌病灶在平扫T1WI上多呈等、低信号，在 T2WI上多呈等信号或稍高信号，仅少数呈低信号，在 T2WI（FS）上肿瘤呈稍高信号，仅少数呈低信号，增强扫描（VIBE）肿瘤呈明显中度（等同宫体强化）强化，部分病例轻度强化。MRI对宫颈癌的定位准确率为97.01%（65/67），分期总准确率为86.56%（58/67），临床分期总准确率为71.64%（48/67），MRI对宫颈癌的分期总准确率高于临床分期总准确率(χ2=5.786，P<0.05)。［结论］ MRI对宫颈癌的定位及诊断准确率较高，可作为宫颈癌诊断的常规检查。术前分期中MRI较临床有明显优势，尤其对Ⅱb及以上期别病例，可作为中晚期宫颈癌术前评估的常规检查方法。 |

| Abstract：［Purpose］ To evaluate the value of MRI in diagnosis and preoperative staging for cervical cancer.［Methods］ Preoperative MRI scan and dynamic contrast-enhanced performance in 67 cases with cervical cancer were enrolled. Characteristics of lumps image，adjacent tissue invasion and distant organ metastasis were analyzed. MRI stage，clinical stage and pathological stage were compared. ［Results］ Most cervical cancer lesions in the unenhanced T1WI showed equal or low signal，showed equal or slightly higher signal on T2WI，only a few showed low signal. Tumors showed slightly higher signal on T2WI (FS)，only a few showed low signal.Enhanced scan(VIBE) tumors were sharp or moderate (equivalent uterus body enhanced) to strengthen，in some cases soft enhancement. Positioning accuracy rate of MRI for cervical cancer was 97.01%（65/67）. Overall accuracy rate of MRI stage was 86.56%（58/67），and overall accuracy rate of clinical stage was 71.64%（48/67）(χ2=5.786，P<0.05).［Conclusion］ MRI can accurately prompt，lesion size and organs involvement in cervical cancer to make more accurate decision. The MRI stage is superior to the clinical stage. MRI can be used as a routine examination for advanced cervical cancer. |
