3.0T MRI联合多层螺旋CT对宫颈癌患者术前TNM分期及分化程度的诊断价值

Diagnostic value of 3.0T MRI combined with multi-slice spiral CT on preoperative TNM staging and differentiation degree of cervical cancer

目的探讨3.0T磁共振成像(MRI)联合多层螺旋CT(MSCT)对宫颈癌患者术前TNM分期及分化程度的诊断价值。方法回顾性分析165例进行手术治疗的宫颈癌患者的临床资料。根据检查方式的不同将患者分为3组,其中,接受3.0T MRI检查的55患者为MRI组,接受MSCT检查的56例患者为MSCT组,接受3.0T MRI联合MSCT检查的54例患者为联合组。以术后组织病理学结果作为金标准,比较3种检查方法对宫颈癌患者术前TNM分期及分化程度的诊断价值。结果联合组对宫颈癌术前分化程度的诊断准确率为92.6%(50/54),高于MRI组的72.7%(40/55)和MSCT组的71.4%(40/56),差异均有统计学意义(P﹤0.05)。MRI组和MSCT组对宫颈癌术前分化程度的诊断准确率比较,差异无统计学意义(P﹥0.05)。联合组对宫颈癌术前TNM分期的诊断准确率为98.1%(53/54),高于MRI组的72.7%(40/55)和MSCT组的73.2%(41/56),差异均有统计学意义(P﹤0.05)。MRI组和MSCT组对宫颈癌术前TNM分期的诊断准确率比较,差异无统计学意义(P﹥0.05)。结论3.0T MRI和MSCT检查对宫颈癌患者术前TNM分期及分化程度的诊断效能相当,3.0T MRI联合MSCT检查可有效提高对宫颈癌患者术前TNM分期及分化程度的诊断准确率,更适用于在临床中推广应用。

Objective To explore the diagnostic value of3.0T magnetic resonance imaging(MRI)combined with multi-slice spiral CT(MSCT)on preoperation TNM staging and differentiation degree for patients with cervical cancer.Method The clinical data of165patients with cervical cancer underwent surgical treatment were analyzed retrospectively.They were divided into MRI group(examined by3.0T MRI,n=55),MSCT group(examined by MSCT,n=56)and combined group(examined by3.0T MRI combined with MSCT,n=54)according to different examination methods.The diagnostic value of three examination methods for preoperative TNM staging and differentiation degree was compared with the results of postoperative histopathology as the golden standard.Result The diagnostic accuracy rate of preoperative differentiation degree of cervical cancer in combined group was92.6%(50/54),which was higher than those in MRI group(72.7%,40/55)and MSCT group(71.4%,40/56),the differences were statistically significant(P<0.05).There was no significant difference in the diagnostic accuracy rate of preoperative differentiation degree of cervical cancer between MRI and MSCT groups(P>0.05).The diagnostic accuracy rate of preoperative TNM staging of cervical cancer in combined group was98.1%(53/54),which was higher than those in MRI group(72.7%,40/55)and MSCT group(73.2%,41/56),the differences were statistically significant(P<0.05).There was no significant difference in the diagnostic accuracy rate of preoperative TNM staging of cervical cancer between MRI and MSCT groups(P>0.05).Conclusion The efficiencies of3.0T MRI and MSCT are similar in the diagnosis of preoperative TNM staging and differentiation degree in patients with cervical cancer.The combined detection can effectively improve the diagnostic accurate rates of preoperative TNM staging and differentiation degree of cervical cancer,which is more suitable for clinical application.
