摘　　要：目的探讨磁共振背景抑制体部弥散加权成像、T2-脂肪抑制序列在宫颈癌临床分期中的价值,着重比较各序列在病灶检出中的作用及平均阅片时间。方法回顾性分析50例临床病理证实的宫颈癌术前MR常规平扫、T2-SPAIR以及DWIBS、增强资料。分组阅片,比较T2-SPAIR、DWIBS的敏感性及各组平均阅片时间。结果50例中,病灶总数为73。SPAIR组检出病灶数64,检出率88%,诊断符合率约90%,其平均阅片时间约18min。DWIBS组检出病灶数85,检出率100%,诊断符合率85%,其平均阅片时间约14min。"SPAIR+DWIBS"组全部检出病灶并正确诊断,检出率、诊断符合率均100%,其平均阅片时间约8min。结论DWIBS在病灶检出方面敏感性高,结合T2-SPAIR能大大提高病灶检出率以及诊断正确率,从而提高临床分期的准确性。Objective To evaluate the MR sequences and its diagnostic value in the clinical staging of uterus cervical carcinoma. Methods 50 cases with clinical-hlstologically proven to be uterus cervical carcinomas were performed with MRI routine scan,T2-SPAIR, DWIBS. And the sensitivity and average review time were compared by groups. Results Among these cases, the number of the lesions was 73. The lesions detected by Group of SPAIR, DWIBS and ＂DWIBS ＋ T2-SPAIR＂ were 64,85,73,respectively. The detective rate was 88%, 100%, 100%, respectively. And the average review time were 18min, 14min, 8min,respectively. Conclusion MRI, especially, DWIBS, plays an important role in the differential diagnosis and clinical staging of uterus cervical carcinoma.
