目的 探讨阴道彩超诊断宫颈癌的临床应用价值及宫颈癌的声像图特征。方法 本文对12 0例经手术与病理证实的宫颈癌患者的二维声像图和CDFI表现进行了回顾性分析。结果 中晚期宫颈癌的阴道彩超声像图表现具有特征性,可分宫颈增大、宫颈部肿块、宫颈部边界呈虫蚀状的液暗区,合并宫腔内积液,宫颈外浸润性肿块等图像改变,宫颈处血流信号丰富,呈“火球样”改变[4 ] ;而早期宫颈癌宫颈无明显增大,仅见宫颈管内强光斑,血流信号增多。宫颈部动脉阻力指数最大为0 .6 1,最小0 .2 7,平均0 .39。结论 经阴道彩超对宫颈癌术前判断病变范围、侵犯范围、鉴别诊断都有较大的价值,可作为宫颈癌治疗前常规的辅助检查方法[2 ] 。
Objective To investigate the clinical value of vaginal ultrasound in the diagnosis of cervical cancer and the characteristics of cervical cancer. Methods This study retrospectively analyzed the two-dimensional sonographic features and CDFI findings of 120 patients with cervical carcinoma confirmed by surgery and pathology. Results The results showed that the vaginal color echography of middle and late stage cervical cancer showed characteristic features, which could be divided into cervical enlargement, cervical mass and cervical area with worm-eaten fluid dark area, intrauterine effusion and extracapsular infiltrative mass And other images change, the cervix is rich in blood flow signals, was “fireball-like” change [4]; and early cervical cancer did not significantly increase the cervix, only to see the cervical canal strong spots, increased blood flow signals. Cervical artery resistance index was the largest 0. 6 1, the smallest 0. 2 7, an average of 0.39. Conclusion Transvaginal ultrasound for cervical cancer preoperative determine the scope of the lesions, the scope of violations, differential diagnosis have a greater value, can be used as a routine cervical cancer screening before treatment [2].
