目的分析探讨宫颈癌MRI分期与妇科检查分期的临床诊断价值。方法 46例因可疑宫颈癌首次入院患者作为研究对象,分别进行宫颈癌MRI分期和妇科检查分期诊断,并对比两种诊断方式的诊断符合率。结果 36例宫颈癌MRI表现及分期与手术、临床分期一致,诊断符合率为78.3%(36/46),本组病例病灶显示率为100.00%,病灶准确定位率为87.0%(40/46),2例Ⅰb期临床高估为Ⅱa期,2例Ⅱa期MRI低估为Ⅰb期、1例临床诊为Ⅰb期,4例Ⅱb期MRI低估为Ⅱa期,1例Ⅱb期临床诊为Ⅲa期,2例Ⅳ期临床分别诊为Ⅲa、Ⅱb期。结论宫颈癌MRI分期的诊断符合率高,特别是在Ⅲa期以上肿瘤分期明显优于临床,在淋巴结转移方面的预测价值较高,可弥补妇科检查的不足。
Objective To analyze the clinical diagnostic value of MRI staging and gynecological examination of cervical cancer. Methods Forty-six patients with suspected first-admission cervical cancer were divided into two groups according to MRI staging and gynecological examinations. The diagnostic coincidence rates of the two diagnostic methods were compared. Results The MRI findings and staging of 36 cases of cervical cancer were consistent with those of surgery and clinical stage. The diagnostic coincidence rate was 78.3% (36/46). The lesions showed 100.00% in this group and the accuracy rate of lesions was 87.0% (40/46) , 2 cases of stage Ⅰb clinical overestimate for stage Ⅱ a, 2 cases of stage Ⅱ a MRI underestimation for stage Ⅰ b, 1 case of clinical diagnosis of stage Ⅰ b, 4 cases of Ⅱ b period MRI underestimate the Ⅱ a period, 1 case Ⅱ b period of clinical diagnosis for stage Ⅲ a, Two cases of stage Ⅳ clinical were diagnosed as Ⅲ a, Ⅱ b period. Conclusion The diagnostic accuracy of MRI staging of cervical cancer is high. Especially in stage Ⅲ a, the staging of tumor is better than that of clinical stage, and the predictive value in lymph node metastasis is high, which can make up for the deficiency of gynecological examination.
