目的回顾性分析急性阑尾炎的声像图特点,探讨高频与低频超声(以下简称高低频超声)在急性阑尾炎诊断中的价值。方法对52例临床诊断为急性阑尾炎的患者分别用高低频超声检查,分析图像特点,对比不同条件下阑尾显示的结果。并与手术病理对照。结果52例患者均经手术病理证实为急性阑尾炎。超声诊断急性阑尾炎48例,超声诊断符合率92.31%,其中低频为32.69%,高频为92.31%。结论高低频超声联合应用能明显提高肿大阑尾的显示率,可作为急性阑尾炎诊断的首选方法。
Objective To retrospectively analyze the characteristics of acute appendicitis and discuss the value of high-frequency and low-frequency ultrasound (hereinafter referred to as high and low frequency ultrasound) in the diagnosis of acute appendicitis. Methods Fifty-two patients with acute appendicitis were examined by high and low frequency ultrasonography, the features of the images were analyzed, and the results of appendix display under different conditions were compared. And compared with surgical pathology. Results All 52 patients were proved to be acute appendicitis by surgery and pathology. Ultrasound diagnosis of 48 cases of acute appendicitis, ultrasound diagnosis coincidence rate of 92.31%, of which 32.69% low frequency, high frequency of 92.31%. Conclusion Combined use of high and low frequency ultrasound can significantly improve the display rate of enlarged appendix, which can be used as the first choice for the diagnosis of acute appendicitis.
