经阴道超声造影在宫颈癌分期中的应用价值及其造影模式分析

Application Value of Transvaginal Contrast-enhanced Ultrasonography in Cervical Cancer Staging and Its Model Analysis

目的:分析经阴道超声造影(TVS-CEUS)测量宫颈癌病灶浸润深度、大小对宫颈癌术前分期的应用价值;并归纳总结不同临床分期宫颈癌的TVS-CEUS灌注模式。方法:回顾性分析43例宫颈癌患者的TVS-CEUS图像特征,并以病理结果为标准,比较TVS-CEUS、MRI在病灶浸润深度、病灶大小之间的差异性;以正常子宫TVS-CEUS灌注模式做对比,归纳总结不同临床分期宫颈癌的TVS-CEUS灌注模式。结果:TVS-CEUS可清晰显示病灶边界,所测量病灶浸润深度及大小与病理结果比较差异无统计学意义(P>0.05),与MRI比较差异亦无统计学意义(P>0.05);不同临床分期宫颈癌的TVS-CEUS灌注模式不同。结论:TVS-CEUS测量病灶浸润深度及大小与病理结果接近,可为临床分期及选择合适的治疗方案提供重要依据;不同的造影灌注模式可较好地反映宫颈癌的不同临床分期。

Objective:To analyze the value of transvaginal contrast-enhanced ultrasonography(TVS-CEUS) in measuring the depth and size of cervical cancer lesions in preoperative staging of cervical cancer, and summarize the TVS-CEUS perfusion patterns of cervical cancer in different clinical stages.Methods:The TVS-CEUS image features of 43 patients with cervical cancer were analyzed retrospectively and compared TVS pathological results-CEUS、MRI the difference between the depth and size of the lesion;compare the normal uterine TVS-CEUS perfusion patterns and summarize the TVS-CEUS perfusion patterns of cervical cancer in different clinical stages.Results:TVS-CEUS the boundary of the lesion could be clearly displayed. There was no significant difference between the depth and size of the lesion and the pathological results(P>0.05), and there was no significant difference with the MRI(P>0.05). The TVS-CEUS perfusion patterns of cervical cancer in different clinical stages were different.Conclusion:TVS-CEUS Measurement of infiltration depth The degree and size are close to the pathological results, which can provide an important basis for clinical staging and selection of appropriate treatment schemes, and different perfusion patterns can better reflect the different clinical stages of cervical cancer.
