| 摘 要： | 目的:探讨儿童小气道病变的最佳影像学检查方法及表现特征。方法:对100例有小气道阻塞肺功能改变患儿的胸部X线片、螺旋CT及高分辨力CT表现进行比较。结果:高分辨力CT对细支气管壁增厚、树芽征、空气潴留、马赛克征等征象的显示数量最多,螺旋CT和胸部X线片几乎不能显示,统计学有显著性差异(P<0.05)。结论:高分辨力CT在细支气管壁增厚、树芽征、空气潴留、马赛克征等小气道病变征象的显示方面明显优于螺旋CT,是显示小气道病变的最佳、无创的影像学检查方法。

| Abstract: | Objective： To investigate the best imaging examination methods for children＇s small airways disease and the imaging characters of small airways disease. Methods： One hundred abnormal children with small airways diseases from Oct. 2004 to Dec. 2007 were examined, then the manifestations of chest X-ray, spiral computed tomography and high-resolution computed tomography were compared. Results： Different imaging signs, such as tree-in-bud pattern, bronchial wall thickening, mosaic perfusion pattern, bronchial mucoid impaction, bronchial dilatation, displayed well in high resolution computed tomography, and showed poor in chest X-ray and spiral computed tomography （ P 〈0.05）. Conclusion： For the display of tree-in-bud pattern, bronchial wall thickening, mosaic perfusion pattern, bronchial mucoid impaction, bronchial dilatation, high-resolution computed tomography is the best and atraumatic methods. |
