摘要 目的探讨MRI在宫颈癌诊断及临床分期中的应用价值。方法对62例宫颈癌患者在术前进行MRI检查,分析其MRI成像特点,参照FIGO制订的标准,对MRI结果进行分期并与手术病理结果进行对比。结果宫颈癌MRI表现为类圆形或不规则形肿块,T1WI呈等信号或低信号,T2WI呈高信号,与宫旁脂肪、子宫内膜高信号及宫颈基质低信号有良好对比,T1WI增强扫描,肿瘤均有不同程度强化。MRI分期准确性为88.71%,特异性为90.16%。结论磁共振成像技术具有良好的组织分辨率和多序列、多方位成像特点,能清楚显示肿瘤大小、部位及侵犯程度,为宫颈癌诊断和分期提供了更加可靠的客观依据,有利于临床制定合理的治疗方案。
