多层螺旋CT重组图像诊断先天性气管支气管发育异常

目的:探讨多层螺旋CT(MSCT)图像重组在诊断先天性气管支气管发育异常中的临床应用价值,提高对气管支气管发育异常的影像学表现的认识.方法:回顾性分析32例经多层螺旋CT图像重组诊断的先天性气管支气管发育异常影像学表现.结果:本组32例中食管-气管瘘13例,气管支气管壁发育异常11例,先天性气管支气管分支异常8例,其中25例合并其它部位的畸形.结论:多层螺旋CT图像重组可以多方位全面观察气管、主支气管、段及亚段支气管的形态、走行、管径及与周围组织的关系,明显提高了本病的诊断准确性,并能明确胸部合并的其它畸形,已成为本病的首选检查方法.

Application of MSCT Reconstruction in Diagnosing Congenital Heteroplasia of Tracheal Bronchs

Objective:To discuss the value of multislice spiral computed tomograph (MSCT) and CT reconstruction in diagnosing the congenital heteroplasia of tracheal bronchus and to improve the understanding of the presentation of congenital heteroplasia of tracheal bronchus.Methods:The presentation of thirty-two cases with congenital heteroplasia of tracheal bronchus approved by the multislice spiral computed tomograph (MSCT) and the CT reconstruction was reviewed and analyzed.Results:In the 32 cases,13 cases have esophago-tracheal fistula;11 cases,dysplasia of wall of tracheal bronchus;8 cases,abnormal branches of tracheal bronchus.In addition,25 cases were complicated with varying degrees of dysplasia in other parts.Conclusion:Using multislice spiral computed tomograph examination and CT reconstruction,we can carry out an overall observation of the shape,course and caliber of trachea,main bronchus,and segment bronchus and raise the diagnostic accuracy.At the same time,we can find more abnormalities in other parts of the body.It is the examination method of first choice.
