【摘要】：目的研究磁共振成像(MRI)动态增强技术对宫颈癌术前分期和诊断的准确度、特异性和灵敏度。方法选取成都医学院第一附属医院2013年8月~2015年12月收治的42例宫颈癌患者作为研究对象,其中18例ⅠB~ⅡA期的患者采用广泛子宫全切术联合盆腔淋巴结清扫术,24例ⅡB期和大于ⅡB期的患者采用开腹关键部位活检术联合盆腔淋巴结活检术,将术后病理学诊断结果确定为对宫颈癌的诊断金标准。所有患者均采用超导MRI仪进行扫描,对盆腔进行常规性MRI平扫序列T1WI、T2WI和DWI,并注射Gd-DTPA进行动态X椙可琛７治龌颊進RI检查分期、术前临床分期和术后病理学分期MRI资料及阴道受累、深肌层浸润、淋巴结转移和宫旁浸润情况,计算其特异性和灵敏度。结果所有患者的术前临床分期、MRI检查分期与术后病理学分期比较,差异有统计学意义(P0.05);术后病理学分期与MRI检查分期比较,差异无统计学意义(P0.05),术前临床分期与MRI检查分期比较,差异有统计学意义(P0.05)。将术后病理学分期作为对照,MRI检查分期的准确度为94.5%,而术前临床分期的准确度为75.8%。MRI诊断和术后病理学诊断对深肌层浸润、阴道受累、宫旁浸润和淋巴结转移的灵敏度和特异性均较高,但差异无统计学意义(P0.05)。结论动态增强MRI检查对宫颈癌患者术前进行分期,准确度较高,对阴道受累、深肌层浸润、淋巴结转移和宫旁浸润的敏感度和特异性均较高,可将其作为宫颈癌术前分期的首选方法。
