摘要 目的:探讨宫颈癌术后复发的MRI诊断价值。方法对52例宫颈癌术后疑似复发患者,采用常规SE序列行轴位T1WI、T2WI、DWI,矢状位T2WI及冠状位T2脂肪抑制盆腔扫描,其中38例行Gd-DTPA增强扫描。MRI检查结果与再次手术、穿刺活检病理检查或临床随访结果进行比较。结果37例患者经再次手术(切除、探查)或穿刺活检病理检查证实为复发,MRI表现为骶前及盆腔肿块,T1WI呈等、低信号,T2WI呈稍高混杂信号,DWI呈高亮信号。复发病灶侵犯膀胱11例、侵犯直肠8例,腹股沟淋巴结及盆腔淋巴结肿大12例,骨转移10例。另15例经临床随访、影像学检查证实为术后改变。结论 MRI检查在宫颈癌术后复发的诊断有重要临床价值,可以明确复发肿瘤侵犯范围,鉴别宫颈癌术后复发与纤维瘢痕。
