摘要 目的探讨高分辨(high-resolution,HR)MRI和经阴道超声检查(transvaginal ultrasound, TVS)对深部浸润型子宫内膜异位症(deep infiltrating endometriosis, DIE)的诊断价值。方法回顾性分析85例DIE患者HRMRI和TVS检查,所有病例均同期行腹腔镜检查,观察分析宫骶韧带、直肠阴道隔、直肠-乙状结肠,将影像诊断与术中所见和病理进行对照,分别计算HRMRI和TVS对不同解剖部位的诊断准确性、灵敏度、特异度、阳性似然比(LR+)、阴性似然比(LR-)。采用配对四格表资料χ~2检验HRMRI和TVS两种检查方法诊断差别,按a=0.05为标准。结果 HRMRI和TVS对左侧宫骶韧带诊断的准确性、灵敏度、特异度、LR+、LR-分别为85.9%vs 77.6%、81.8%vs 72.7%、93.3%vs 86.7%、12.27 vs 5.45、0.195 vs 0.315,两种方法无统计学差异;HRMRI和TVS对右侧宫骶韧带诊断的准确性、灵敏度、特异度、LR+、LR-分别为94.1%vs 68.2%、85.7%vs 64.3%、66.6%vs 86.7%、2.571 vs 4.821、0.241 vs 0.315,两种方法存在统计学差异;HRMRI和TVS对直肠阴道隔诊断的准确性、灵敏度、特异度、LR+、LR-分别为98.8%vs 80%、63.3%vs 50%、98.2%vs 96.4%、34.8 vs 13.75、0373 vs 0.519,两种方法无统计学差异;HRMRI和TVS对直肠-乙状结肠诊断的准确性、灵敏度、特异度、LR+、LR-分别为97.6%vs 60%、88.5%vs 57.4%、91.7%vs 66.7%、10.623 vs 1.148、0.105 vs 0.639,两种方法有统计学差异。结论 HRMRI和TVS作为无创性术前检查,均能较好的评估DIE病变,有利于术前指导临床手术方式的选择。HRMRI对DIE的诊断价值高于TVS,两者在右侧宫骶韧带和直肠-乙状结肠的诊断上有统计学差异,HRMRI在直肠、左侧宫骶韧带和直肠阴道隔DIE诊断评估中优于TVS,TVS对右侧宫骶韧带诊断特异性高。
