| 目的：评价多层螺旋CT三维重建及仿真内窥镜技术对气管支气管异物的诊断价值。方法：对20例支气管异物、1例气管异物、1例先天性气管性支气管发育异常、1例气管良性肿瘤患儿行多层螺旋CT检查并进行三维重建及仿真内窥镜技术显示气管支气管病变；三维重建技术包括多平面重建、最大密度投影、最小密度投影、表面遮盖显示和容积再现，CT仿真内窥镜对气管支气管异物的显示与支气管镜所见具有一致性。结果：多层螺旋CT三维重建及仿真内窥镜可准确、直观地显示气管支气管异物的位置、大小、形态、密度及阻塞程度。结论：多层螺旋CT三维重建及仿真内窥镜可准确评价气管支气管异物，是一种准确无创性诊断方法，为临床治疗提供直观的影像学资料，具有较高的临床诊断及指导价值。 |
| Objective: To evaluate multi-slice spiral CT three-dimensional reconstruction and virtual endoscopy to the diagnosis of tracheobronchial foreign bodies. Methods: 20 cases of bronchial foreign body, 1 case tracheobronchial foreign body, 1 case of congenital tracheal bronchial dysplasia, 1 in children with benign tracheal line of multi-slice spiral CT examination and three-dimensional reconstruction and virtual endoscopy showed tracheobronchial lesions; three-dimensional reconstruction techniques include multi-planar reconstruction, maximum intensity projection, minimum intensity projection, surface shaded display and volume rendering, CT virtual endoscopy of the tracheobronchial foreign bodies in the display and bronchoscopic findings consistent. Results: Multi-slice spiral CT three-dimensional reconstruction and virtual endoscopy can accurately and intuitively display the tracheobronchial foreign body location, size, shape, density and degree of obstruction. Conclusion: Multi-slice spiral CT three-dimensional reconstruction and virtual endoscopy can be an accurate assessment of tracheobronchial foreign body, is an accurate non-invasive diagnostic method for the clinical treatment of the image data to provide intuitive, and the higher the value of clinical diagnosis and guidance. |
