摘　　要：目的　评价超声对中心型肺癌的诊断价值。方法　对胸部X线或CT检查诊断为中心型肺癌伴肺实变(阻塞性肺炎、肺不张 )的 6 1例患者进行超声检查。结果　实变肺的声像图表现为楔形或三角形低回声或等回声 ,肺癌为肺门附近的低回声结节或实变肺内的强回声肿块。CT在确定支气管阻塞方面优于超声 (P <0 .0 0 1) ,而在显示肺实变及确定阻塞的肿瘤方面CT和超声没有统计学意义 (P >0 .0 5 )。Objective This study was to evaluate the efficacy of ultrasonography(US) for diagnosis of central lung carcinoma.Methods We performed US studies from 61 cases to have lung tumors associated with the consolidated lung(obstructive pneumonitis,obstructive atelectasis)detected by roentgenbographs or CT.Result The US findings in the consolidated lung included an iso-or hypoechoic area with a wedge or triangular shape.The presumed obstructing tumor was seen as a hypoechoic nodule near the hilium or as a well-delfined hyperechoic mass inside the consolidated lung.Computed tomography(CT)was superior to US in demonstrating the bronchial obstruction(P<0.001).However,there were no significant differences between CT and US in demonstrating the obstructing tumor and the consolidated lung(P>0.05).Conclusion It is concluded that US is useful adjunct diagnostic techniques for lung tumor patients with obstructive pneumonitis and atelectasis.
