MRI联合经阴道彩超在宫颈癌诊断及分期判断中的价值分析

The Value Analysis of MRI Combined with Transvaginal Color Ultrasound in the Diagnosis and Staging Judgment of Cervical Cancer

目的探讨MRI联合经阴道彩超在宫颈癌诊断及分期判断中的应用价值。方法对93例宫颈癌患者的临床资料进行研究,所有患者均先后行MRI及经阴道彩超检查,比较不同检查方法的诊断效能及在分期判断中的符合率。结果MRI联合经阴道彩超诊断在2 cm以内肿瘤直径、50%以内间质浸润、阴道浸润、宫旁受累及淋巴结转移中的敏感性、特异性、准确性及阳性预测值均显著高于MRI与经阴道彩超单独诊断,差异有统计学意义(P<0.05);MRI联合经阴道彩超在宫颈癌临床分期中的诊断符合率显著高于MRI与经阴道彩超单独诊断,差异有统计学意义(P<0.05)。结论MRI联合经阴道彩超可有效判断肿瘤直径、临床分期、间质及阴道浸润、宫旁受累及淋巴结转移情况,其诊断效能显著高于MRI与经阴道彩超单独检测,可为临床确立治疗方案提供有力的参考依据,具有较高的应用价值。

Objective To explore application value of MRI combined with transvaginal color ultrasound in the diagnosis and staging judgment of cervical cancer.Methods 93 patients with cervical cancer were selected as the subjects.All patients underwent MRI and transvaginal color ultrasound examination,compared the diagnostic efficacy of different examination methods and the conformity rate in staging judgment.Results MRI combined with transvaginal ultrasound diagnosis within 2 cm,interstitial invasion within 50%,vaginal invasion,paraventricular involvement,Sensitivity,specificity,accuracy,and positive predictive value in lymph node metastasis were significantly higher than those of MRI and transvaginal color ultrasound alone diagnosis(P<0.05).The diagnostic conformity rate of MRI combined with transvaginal color ultrasound in the clinical staging of cervical cancer was significantly higher than that of MRI and transvaginal color ultrasound alone(P<0.05).Conclusion MRI combined with transvaginal color ultrasound can effectively determine the tumor diameter,clinical staging,interstitial and vaginal invasion,parametrial involvement and lymph node metastasis.Its diagnostic efficiency is significantly higher than MRI and transvaginal color ultrasound alone detection,and can provide a powerful reference for establishing clinical treatment plan and high application value.
