多层螺旋CT后处理技术对气管支气管异物的诊断价值

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。

Multi-Slice Spiral CT Post-Processing Techniques for the Diagnosis of the Tracheobronchial Foreign Bodies

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 ease 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.
