摘要
目的研究超声诊断急性阑尾炎的声像图特征及其价值。方法对121例经手术证实的初诊疑似急性阑尾炙患者用高低频探头相互结合的方法，先用低频探头（频率：3．5MHz）进行右下腹及全腹检查后，再改用高频探头（频率：75-100MHz）反复扫查阑尾区，观察各类型急性阑尾炎的声像图表现，并与病理结果对照i，结果超声诊断急性阑尾炎的准确性为880％。，结论超声诊断急性阑尾炎为临床提供了一个直接、简便、安全的方法。
Objective To study the characteristics of sonogram of acute appendicitis with ultrasound and its clinical value. Methods Totally, 121 patients with suspected acute appendicitis were observed with low and high frequency ultrasound. Both right lower quadrant and total abdomen of these patients were scanned using low frequency probe （3.5 MHz）, subsequently the area of appendix was scanned carefully with high frequency probe （7.5-10.0 MHz） further. Sonographic appearances of different types of acute appendicitis were observed anti compared with pathologic results. Results The accuracy of ultrasound in the diagnosis of acute appendicitis was 88% in accordance with the pathologic results. Conclusion Ultrasound diagnosis of acute appendicitis provides a direct, convenient and safe alternative method, which can be used as a reliable diagnostic reference clinically.
