摘　　要：目的分析宫颈癌的MRI表现,探讨宫颈癌的MRI诊断及在分期中的价值。方法我院53例经病理确诊为宫颈癌患者在术前或治疗前后行MRI检查,通过观察肿瘤的位置、信号及侵犯范围,将宫颈癌MRI的影像学分期与病理结果进行比较。结果宫颈癌T2WI较易发现病变,呈稍高或高信号,与低信号的宫颈基质和高信号的子宫内膜、宫旁组织形成良好的对比,T1WI呈等或稍低信号,增强T1WI压脂扫描可见轻度强化。定位诊断的准确率达94.3%,分期准确度达成88.7%。结论 MRI在宫颈癌的诊断及分期中起着重要作用,能为宫颈癌提供客观、准确的判断,有利于选择合理的治疗计划。Objective To investigate the value of magnetic resonance imaging （MRI） in the diagnosis and staging of cervical cancer. Methods The MRI signs before and after treatment of 53 cases of cervical cancer confirmed by pathology were retrospectively analyzed. The MRI staging were compared with pathological results. Results Lesions of cervical cancer was easier to be found on T 2 WI, showing slightly higher or high signal, forming a good contrast with the low signal of cervical stroma and the high signal of endometrium and parametrium. Cervical cancer shows slightly lower signal in T 1 WI image and enhanced T 1 WI fat suppression scan showed mild enhancement. The accuracy of tumor localization is about 94.3%. The staging accuracy is 88.7%. Conclusion MRI plays an important role in the diagnosis and staging of cervical cancer. It can provide objective and accurate judgment of cervical cancer, which helps to choose a reasonable treatment plan.
