摘　　要：目的探讨二维基波和自然谐波条件下,结合彩色多普勒超声在急性阑尾炎检查中的实用价值。方法对166例因腹部疼痛或可疑阑尾炎的患者,分别在二维基波、自然组织谐波和彩色多普勒超声条件下,使用7.0～10.0MHz高频和3.5～4.0MHz普通腹部探头做超声检查,分析阑尾区的图像特点,对比不同频率的探头对于阑尾显示的效果。结果全部病例经手术、病理或治疗后随访观察证实。166例病例中,超声确诊急性阑尾炎136例(81.9%),急性阑尾炎合并周围脓肿或炎性包块30例(18.1%),急性阑尾炎的彩色血流信号显示率62.0%。结论高频超声在显示肿大阑尾结构上更具有特异性,能明显提高肿大阑尾的显示率。彩色多普勒血流有助于急性阑尾炎的诊断。二维基波、自然谐波和彩色多普勒超声检查可作为临床诊断急性阑尾炎的重要依据。Objective Evaluation of fundamental imaging,tissue harmonic imaging and color Doppler imaging(CDI) in the diagnosis of acute appendicitis.Methods Fundamental imaging,tissue harmonic imaging and CDI were performed in 166 patients with abdominal pain or suspected acute appendicitis.We used 7.0-10.0 MHz high frequency and 3.5-4.0 MHz low frequency transducers.Results There were 166 cases including 136 cases(81.9%) with acute appendicitis,30 cases (18.1%) with periappendicular inflammation and abscess.All cases were confirmed by operation and pathology or treatment and follow-up.Conclusions High frequency ultrasound can evidently improve displaying enlarged appendixes.Color Doppler imaging is useful for the diagnosis of acute appendicitis.Two-dimensional fundamental imaging,tissue harmonic imaging and color Doppler imaging provide important evidence for the clinic diagnosis of acute appendicitis.
