| 中文摘要:目的 通过与彩色多普勒超声对比,探讨超声造影在睾丸扭转诊断中的临床应用价值。方法 回顾性分析43例经手术或临床随访证实的睾丸扭转患者的超声造影表现,并与彩色多普勒超声的诊断性能进行比较。结果 超声造影时,7例完全扭转型患侧睾丸内未见造影剂填充,睾丸周围组织环状增强,呈"晕圈征"。36例不完全扭转型患侧睾丸内部均有造影剂填充,但可见局部造影剂缺损区,与健侧睾丸比较,增强开始时间和达峰时间均明显延长,达峰强度低于正常睾丸组织,呈低增强。超声造影和彩色多普勒超声诊断完全扭转型睾丸扭转的准确率均为100%,两种方法比较差异无统计学意义(χ2=0.000,P=1.000),超声造影诊断不完全扭转型睾丸扭转的准确率为100%,彩色多普勒超声诊断不完全扭转型睾丸扭转的准确率为83.3%,两种方法统计学比较差异有统计学意义(χ2=4.2,P < 0.05)。结论 超声造影和彩色多普勒超声在诊断完全扭转型时有很好的一致性,超声造影诊断不完全扭转型的准确率优于彩色多普勒超声。超声造影可准确判定睾丸缺血受损的范围及程度,可作为睾丸扭转诊断评估的重要影像学方式。 |

| Abstract:Objective To investigate the value of contrast-enhanced ultrasound (CEUS) in diagnostic of testicular torsion by compared with color doppler ultrasound. Methods Clinical data of 43 patients diagnosed with testicular torsion by operation or clinical follow-up were included in this retrospective study. The capabilities in diagnostic of testicular torsion have been compared between CEUS and color doppler ultrasound. Results There was no significant enhancement in 7 cases of complete torsional testicles,ring enhancement of the surrounding tissue and the "ring sign" were displayed on CEUS.CEUS in 36 patients of them revealed nonfilling of contrast in incomplete testicular torsion. Arrive time and time to peak were delayed than those of normal contralateral testicles, and the peak intensity were lower than normal testis and Low enhancement were displayed on CEUS. The diagnostic accuracy of CEUS and color doppler ultrasound in complete testicular torsion was 100% without significant difference (χ2=0.000,P=1.000). The diagnostic accuracy of CEUS in incomplete testicular was 100% and which was 83.3% of color Doppler ultrasound.It was statistically significant difference between groups.(χ2=4.2,P < 0.05). Conclusion CEUS and color Doppler ultrasound have similar capabilities in diagnostic of complete testicular torsion.CEUS is better than color doppler ultrasound in diagnostic of incomplete testicular torsion.CEUS can accurately determine the scope and extent of impaired testicular and can be an important imaging methods in evaluation prior to operation of testicular torsion. |
