摘要
目的:探索多层螺旋CT图像后处理技术对于支气管结石的诊断价值,并分别与常规轴位图像及支气管镜的诊断结果进行对照分析。方法:回顾性分析11例经支气管镜检查证实的支气管结石患者的胸部CT,由工作站进行多平面重组(MPR)及仿真内窥镜(VE)处理,观察结石与支气管的位置关系,及结石所在的肺段。结果:所有病例均能经后处理图像发现结石所在支气管。支气管镜发现14粒结石,常规轴位图像发现结石11粒,后处理图像发现结石14粒。结论:多层螺旋CT图像后处理技术对于支气管结石的检出率与支气管镜的检出率接近,同时能为临床早期发现支气管结石并制定治疗方案,提供科学和客观的影像依据。
Objective To explore the value of multi-slice CT post-processing technique in diagnosis of Broncholithiasis,comparative analysis of the results of normal axial pictures and bronchoscopy.Methods 11 cases of broncholithiasis confirmed by fibrobronchoscopy were analyzed retrospectively.All original images were transferred to workstation for image post-processing.The best depictive MPR,VE images were acquired to observe the relative location of stones and bronchus,and the lung segment where the stones are located.Results 14 stones were found by bronchoscopy.11 stones were found by normal axial images.All Fourteen stones can be found by the post-processing images.Conclusion The detected rate of broncholithiasis by post-processing inages is close to fibrobronchoscopy.Reconstruction technique of multislice spiral CT could accurately demonstrate the broncholithiasis,and provide scientific and objective foundation for early detection and the formulation of clinical treatment programs.
