MR、CT及超声对宫颈癌宫旁浸润的对照分析(1)
摘要：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%，判斷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。

Abstract：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.

宫颈癌(cervical cancer)是目前最常见的女性生殖系统恶性肿瘤，近年来发病率有明显上升并呈现年轻化趋势，高发年龄为45～65岁[1]。术前宫颈癌的诊断依据主要依靠临床宫颈活检及组织病理学，而是否有宫颈病灶宫旁浸润主要根据超声(US)、CT和MRI检查进行判断。本文回顾性地分析了53例宫颈癌患者运用US/CT/MR检查的影像学检查诊断与术后病理结果进行对照分析，以其在术前进一步提高宫颈癌宫旁浸润诊断及评估的准确性和可靠性，为宫颈癌的临床治疗提供更全面的科学依据。
1资料与方法
1.1一般资料
收集了我院自2012年2月～2016年12月在妇产科经病理组织检查证实为宫颈癌而接受手术的患者84例，年龄25～77岁，平均年龄(53±10.7)岁；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。所有程序经过医院伦理委员会审核，患者及家属知情同意。
1.2方法
1.2.1超声检查 使用Aloka-SSD4000及SIEMENS-ACUSON Sequoia512彩色多普勒超声仪，经阴道探头频率5.5～7.5 MHz，扫描深度8 cm，扫描角度60°～240°。
1.2.2 CT检查 使用GE8800多排全身螺旋CT扫描机，技术条件为120 kV，120 mA，1.8 s，先行腹盆腔横断面平扫，层厚5 mm，层间距5 mm，动态增强扫描使用非离子型对比剂碘海醇250 ml经高压注射器以1.5 ml/s的速率行肘静脉注入腹盆腔扫描并摄片。, 百拇医药(朱宏伟 康莉 谢军舰)
