超声扫查阑尾炎的方法及图像分析

DISCUSSION ON THE BEST METHOD OF ULTRASONIC SCANNING APPENDICITIS

目的探讨超声检查阑尾炎的方法及图像。方法 180例经手术治疗及病理检查证实阑尾炎的术前超声检查方法及图像结果进行回顾性对比分析。先使用低频超声探头,探头频率3.5MHz,再使用高频超声探头,频率为7～10 MHz,在腹部及阑尾区探查,然后二者联合应用,最后加上彩色多普勒血流,观察阑尾及周围情况。结果 180例患者的低频及高频超声检查方法不同,显示率不同,各有优缺点,联合应用低频及高频探头再加彩色多普勒诊断阑尾炎显示率最高。结论普通腹部低频探头与高频线阵探头再加彩色多普勒联合应用对阑尾炎的诊断符合率明显提高,正确使用不同频率超声探头是扫查阑尾炎的最佳方法。

Objective To explore the best method of ultrasonic scanning appendicitis. Methods 180 pa- tients treated by operation and pathological examination confirmed appendicitis preoperatively ultrasound examination method and image findings were retrospectively analyzed. First use of low - frequency ultrasound probe, the probe fre- quency 3.5MHz, then use high frequency ultrasound probe, the frequency 7 - 10MHz, in the abdomen and the ap- pendix area exploration, and the combination of the two, the last with color Doppler flow, observating the appendix and the ambient condition. Results In 180 cases of patients with low frequency and high frequency ultrasound exami- nation method, display rate is different, each have advantages and disadvantages, combined with the application of low frequency and high frequency probe and color Doppler diagnosis of appendicitis showed the highest rates. Conclu- sion Common abdominal frequency probe with high frequency linear - array probe and color Doppler combined ap- plication in the diagnosis of appendicitis with rate increased significantly. Correct use of the different frequency ultra- sonic probe is the best way to scan appendicitis.
