目的探讨急性阑尾炎的超声影像学特征,应用价值,提高超声诊断符合率.方法回顾性分析我院2013年9月~2014年9月以来,临床诊断为急性阑尾炎并进行阑尾切除的病例,分析其术前的超声影像学特征,并与手术病理诊断进行对比分析.结果 42例患者超声诊断39例,超声诊断符合率92.8%,3例不典型.结论不同病理类型的急性阑尾炎超声图像具有一定特征.尤其是高频超声的使用,可根据阑尾炎各型声像图特征,做出较准确的诊断. “,”Objective To investigate the characteristics of ultrasound imaging of acute appendicitis,application value,improve the coincidence rate of ultrasound diagnosis. Methods Retrospective analysis of our hospital from 2013 September to 2014 since September, the clinical diagnosis of acute appendicitis and appendectomy cascs,ultrasonographic features of preoperative analysis,and the results were compared with operation and pathology. Results Of 42 cases,39 cases were diagnosed with ultrasound,the diagnostic rate of ultrasound was 92.8%,3 cases of atypical. Conclusion There is some characteristics of acute appendicitis ultrasound images of different pathological types.Especially the use of high-frequency ultrasound in appendicitis,according to the characteristics of ultrasonic images,make more accurate diagnosis.
