高频彩超和超声造影在急性附睾炎诊断和评估中的价值研究

目的 探讨高频彩超和超声造影在急性附睾炎诊断和评估中的临床价值。方法 回顾性分析经临床证实的急性附睾炎患者的高频彩超和超声造影特征,并分析健患两侧附睾超声造影定量参数的差异。结果 典型急性附睾炎表现为患侧附睾不规则增大,回声减低,血流信号明显增多增密,频谱呈高速低阻状态;超声造影呈"快进慢出"的特征,患侧附睾造影剂开始增强时间和达峰时间早于健侧附睾,消退时间晚于健侧附睾,达峰强度和曲线下面积高于健侧附睾,差异均有统计学意义（P<0.05）。结论 超声造影可清晰显示急性附睾炎的血流灌注特征,超声造影定量参数可准确反映健患两侧附睾血流灌注的差异,在急性附睾炎早期诊断和并发症的评估方面可以为临床医生提供帮助,超声造影结合高频彩超对准确诊断和评估急性附睾炎具有重要的参考价值。

Value of High Frequency Color Doppler Ultrasound and Contrast-enhanced Ultrasound in the Diagnosis and Evaluation of Acute Epididymitis

Objective To investigate the clinical value of high frequency ultrasound (HFU)and Contrast-enhanced Ultrasound (CEUS) in the diagnosis and evaluation of acute epididymitis. Methods The clinical characteristics of patients with acute epididymitis confirmed by high frequency ultrasound and contrast-enhanced ultrasound were retrospectively analyzed. The quantitative parameters of epididymal contrast-enhanced ultrasound were analyzed. Results Ipsilateral epididymis irregular increased,echo decreased, and blood flow signals increased significantly and density increased. The spectrum was high-speed low-impedance state. Ultrasound showed "fast forward slow" feature. The time of ipsilateral epididymis contrast agent to enhancing and to peak was earlier than contralateral epididymis, and the regression time was later than that in the contralateral epididymis, and the peak intensity and the area under curve were higher than those in the contralateral epididymis. The differences were statistically significant. Conclusion High-frequency color Doppler ultrasound imaging can clearly show the perfusion characteristics of acute epididymitis.Quantitative parameters of contrast-enhanced ultrasound can accurately reflect the difference of epididymal perfusion between the unaffected side and the affected side,which provides clinician with early detection and assessment of complications to acute epididymitis.Contrast-enhanced Ultrasound with high frequency ultrasound has the significant reference value to accurately diagnose and assess acute epididymitis.
