目的 探讨MRI对宫颈癌诊断及对宫颈癌分期的价值。方法 对 3 1例经病理证实的宫颈癌患者行MR检查 ,其中 14例进行了手术。在MR图像上观察原发肿瘤的大小、位置、信号特征及宫旁和盆壁侵犯。对 14例手术患者 ,比较MR所见与手术病理所见。结果 宫颈癌的MRI表现较具特征性 ,T2 WI呈高信号 ,与低信号的宫颈基质有良好的对比 ;T1WI呈等信号或稍高信号。MRI对宫颈癌部位判断的准确率为 10 0 % ,对宫颈癌分期的正确率为 85 7%。结论 MR因具有良好的软组织对比及多方位成像能力 ,能清楚显示肿瘤及宫旁侵犯 ,对宫颈癌诊断和分期明显优于临床和其他影像检查方法 ,应成为宫颈癌术前常规的影像检查方法
Objective To investigate the diagnostic value of MRI for cervical cancer and the value of cervical cancer staging. Methods 31 cases of pathologically confirmed cervical cancer patients underwent MR examination, of which 14 patients underwent surgery. Observed in the MR image of the size of the primary tumor, location, signal characteristics and invasion of paravertebral and pelvic wall. Fourteen cases of surgical patients, compared with MR see the surgical pathology. Results The MRI findings of cervical cancer were more characteristic. T2 WI showed high signal and good contrast with low signal cervical matrix. T1WI showed equal or slightly higher signal. The accuracy of MRI in judging the location of cervical cancer was 100%, and the correct rate of cervical cancer staging was 85.7%. Conclusion MR has a good soft tissue contrast and multi-imaging capabilities, can clearly show the tumor and uterine invasion, the diagnosis and staging of cervical cancer was significantly better than clinical and other imaging methods should be cervical preoperative routine imaging method
