经阴道彩色多普勒超声诊断宫颈病变的价值

The Diagnostic Value of Transvaginal Color Doppler Sonography in Cervical Lesions

目的:评价经阴道彩色多普勒超声(TVCDS)对宫颈病变的诊断价值。材料和方法:对722例受检者进行经阴道超声(TVS)检查,采用彩色多普勒血流显像(CDFI)检测收缩期血流峰值速度(PSV)及阻力指数(RI),并将187例宫颈病变的宫颈活检或手术病理结果与超声结果进行对照。结果:宫颈囊肿、息肉、肥大、肌瘤的二维声像图特征明显,诊断符合率依次为100%、85.4%、92.1%、100%;宫颈癌的诊断符合率62.5%,并可提示周围的浸润情况;宫颈肌瘤组的PSV和RI值显著低于正常宫颈组,宫颈囊肿组和息肉组的PSV和RI值显著低于正常宫颈组;宫颈癌组的PSV显著高于正常宫颈组,RI值显著低于正常宫颈组。结论:TVCDS是一种诊断宫颈病变的重要影像学方法。

Purpose： To evaluate the diagnostic value of transvaginal color Doppler sonography （TVCDS） in cervical lesions. Materials and Methods： 722 patients underwent transvaginal sonography, assessing blood flow peak velocities in systolic （PSV）and resistance index （RI）by color Doppler flow imaging（CDFI） .The findings of ultrasound in 187 patients were compared with their pathologic results. Results： There were specific ultrasonic features in 2-dimensional images of cervical cysts,polypoid,hypertrophy,myoma and carcinoma. Compared with pathologic results, the diagnosis coincidence rate of ultrasound in these lesions were 100% ,85.4% ,92.1% ,100% and 62.5%, respectively. The ultrasound was especially useful in revealing the tissue involvement around the uterine of carcinoma patients. There were also significant difference between PSV and RI of these cervical lesions and that of normal. Conclusion： TVCDS is of great value in the diagnosis of cervical lesions.
