目的探讨宫颈癌经阴道超声的影像特点及在术前分期中的价值。方法选取2016年1-12月佳木斯市中心医院接诊并经病理证实为宫颈癌的75例患者及同期在该院行妇科检查正常者75例为研究对象,回顾性分析宫颈癌患者经阴道超声检查结果、分期准确率及影像特点。结果 75例病理诊断确诊为宫颈癌患者经阴道超声检测出67例,准确率为89.33%;经分期诊断,准确判断出61例,准确率为81.33%,误差14例,误差率为18.67%。经阴道超声检测出的67例患者病灶区造影剂的到达用时、达峰用时及廓清时间均短于正常肌层患者,峰值呈度明显高于正常肌层患者,差异有统计学意义(P<0.05)。结论经阴道超声应用于宫颈癌检测,具有无创、高分辨率、高敏感度的特点,检测中可显示出较小的病灶,可为宫颈癌的确诊、术前分期和治疗方案的制定提供重要信息。
Objective To investigate the characteristics of transvaginal ultrasonography in cervical cancer and its value in preoperative staging. Methods From January to December 2016, 75 patients with cervical cancer confirmed by pathology in Jiamusi Central Hospital and 75 patients with normal gynecological examination in the same hospital during the same period were retrospectively analyzed. Transvaginal ultrasonography Test results, staging accuracy and imaging features. Results The pathological diagnosis of 75 cases of cervical cancer detected by transvaginal ultrasound in 67 cases, the accuracy rate was 89.33%; by staging diagnosis, accurately determine 61 cases, the accuracy rate was 81.33%, the error was 14 cases, the error rate was 18.67%. Transvaginal ultrasound detected in 67 patients with focal area arrival time, peak use time and clearance time are shorter than normal myometrial patients, the peak was significantly higher than the normal myometrial patients, the difference was statistically significant (P < 0.05). Conclusion Transvaginal ultrasonography applied to the detection of cervical cancer has the characteristics of noninvasive, high resolution and high sensitivity. It can show lesser lesions in the examination and may provide important information for the diagnosis, preoperative staging and treatment planning of cervical cancer information.
