MR、CT及超声对宫颈癌宫旁浸润的对照分析

Comparative Analysis of MR,CT and Ultrasound in the Detection of Para Uterine Invasion in Cervical Cancer

目的 探讨MR、CT及超声3种不同影像学方法术前判断宫颈癌宫旁浸润的准确性.方法 回顾性分析了84例宫颈癌患者的病例资料,其中53例患者术前接受了超声(US)检查,同时有27例患者接受了核磁共振(MR)检查,有20例患者接受了CT检查.所有患者均进行了手术治疗,将患者术前影像学检查结果与术后病理诊断进行比较.结果 超声、CT和MRI检查术前判断宫颈癌宫旁浸润的诊断符合率分别为83.00%、80.00%和92.50%,判断宫旁浸润的敏感性为70.00%、73.30%和92.30%.特异性均为100.00%.MRI检查判断宫颈癌宫旁微浸润的符合率、敏感性显著优于CT和US检查(P<0.01).结论 MRI检查术前判断宫颈癌宫旁浸润情况明显优于超声和CT检查.对于宫颈癌宫旁浸润的准确性高,可作为宫颈癌宫旁浸润的诊断及术前分期的首选.

Objective To investigate the effect of MR,CT and ultrasound imaging of 3 different parties before the spell to judge the accuracy of parametrial infiltration in cervical carcinoma.Methods A retrospective analysis of the clinical data of 84 cases of cervical cancer patients,53 patients accepted ultrasound before operation(US)examination,while 27 patients underwent magnetic resonance imaging(MR)examination,20 patients received CT examination.All patients underwent surgical treatment,patients with preoperative imaging the inspection results and postoperative pathological diagnosis were compared.Results Ultrasound,CT and MRI examination in preoperative diagnosis of cervical cancer diagnosis of parametrial coincidence rate were 83.00%,80.00%and 92.50%,sensitivity to determine the para-uterine infiltration was 70.00%,73.30%and 92.30%.Specificity was 100.00%.MRI examination to determine the coincidence rate of uterine cervical microinvasion,the sensitivity was significantly better than the CT and US examination(P<0.01).Conclusion The preoperative evaluation of uterine infiltration of cervical cancer by MRI is superior to ultrasound and CT.High accuracy for uterine infiltration of cervical cancer can be used as the first choice of diagnosis and preoperative staging of uterine infiltration of cervical cancer.
