目的：评价多层螺旋CT三维重建技术对气管支气管淀粉样变的临床诊断价值。方法回顾性分析7例经支气管纤维镜及临床、病理最终确诊为气管支气管淀粉样变的患者，对其进行多层螺旋CT扫描，所有数据均发送到工作站进行三维重建。结果7例病例中，男性4例，女性3例，年龄35~61岁，中位年龄47岁。CT横段位及三维重建技术显示：病变范围长，呈连续性，累及气管2例，累及主支气管4例，累及叶、段支气管达7例，管壁增厚钙化为主，管壁钙化以支气管明显，钙化主要表现为块状或长条状。气管及支气管管腔明显狭窄，所有病例均出现不同程度的管腔狭窄，继发肺部阻塞性炎症5例。结论多层螺旋CT三维重建技术可通过立体、多方位观察气管及支气管情况，明确气管支气管淀粉样变受累范围，了解管壁、管腔情况，可为临床及放射科医生提供更多可靠信息，对准确诊断该病起至关重要的帮助。

Objective To explore the clinical value of MSCT three-dimensional reconstruction technique in tra-cheobronchial amyloidosis(TBA). Methods Retrospective analysis of 7 cases diagnosed as tracheobronchial amyloi-dosis by pathology after bronchial fiberscope biopsy. All patients underwent CT scan and the data was sent to worksta-tion for three-dimensional reconstruction. Results Of all the 7 cases,there were 4 cases of male and 3 cases of fe-male, aging from 35 to 61 years old with the median age of 47 years old.By chest cross-sectional and three dimen-sional CT imaging, TBA had the characteristic features of long extent and continuity. There were 2 cases that involved with trachea,4 cases involved with primary bronchus,and 7 cases involved with segmental bronchus. Tracheobronchial wall was characterized by thickening and calcification, which was obvious in bronchus ,and the calcification shaped as block or strip. The trachea and bronchus luminal stenosis was obvious, There were 5 cases of secondary pulmonary inflammation. Conclusion MSCT three-dimensional reconstruction technique can intuitively observe the wall and the lumen with multi-dimensional, providing more reliable information for the clinical diagnosis of tracheobronchial amyloidosis.
