螺旋CT多平面重建在小儿可疑气道异物诊断中的应用

目的:探讨多层螺旋CT多平面重建(MPR)在不典型X线穿透性异物的诊断价值。方法:对71例可疑呼吸道异物患儿行螺旋CT扫描多平面重建。结果:35例MPR直观显示异物的位置、大小、形态及与周围组织关系,其中气管异物6例、右主支气管异物16例、右下支气管异物5例、左主支气管异物7例、左下支气管异物1例、双侧主支气管异物1例;排除异物35例,手术未证实异物1例。结论:MPR对气管支气管异物显示率高、定位准确,在可疑气道异物诊断及鉴别诊断中有重要意义。

Application of spiral CT MPR for suspicious airway foreign bodies in children

Objective: To evaluate the clinical value of spiral CT multiple planarre construction(MPR) in the diagnosis of atypical airway foreign bodies in children.Method: Seventy-one patients suspected of having airway foreign body received spiral CT multiple planarre construction.Results: All gained clear graphs.The imaging results demonstrated that airway foreign bodies located in trachea in 6 cases, in right primary bronchus in 16 cases,in right lobar bronchus in 5 cases,in left primary bronchus in 7 cases,in left lobar bronchus in 1 case and in both bronchus in 1 case,and non-foreign bodies in other 35 cases.Of the foreign bodies,1 was proved to be ropy secretion by bronchoscopy.Conclusion: By MPR,the airway foreign bodies are well displayed.MPR may play an important role in the diagnosis and differential diagnosis of suspected airway foreign bodies in children.
