摘要

目的探讨主气道阻塞性病变的多层螺旋CT（multi-slice CT， MSCT）后处理价值。方法对70例主气道阻塞性病变患者应用多平面重建（MPR）、仿真支气管镜(CTVB)和容积再现（VR）后处理重建技术进行图像后处理。结果 MSCT后处理技术均能直观地显示主气道阻塞性病变的形态。通过多平面重建测量70例主气道阻塞性病变的面积狭窄率，其中轻度狭窄4例（狭窄率≤50%），中度狭窄21例（50%结论 MPR后处理技术能准确地显示主气道阻塞性病变，可为临床提供有用的价值，而CTVB和VR的临床应用价值有限。

Abstract

Objective To investigate the value of postprocessing techniques of multislice CT for main airway obstructive diseases. Methods The images by multiplanar reformation (MPR)

volume rendering (VR) and CT virtual bronchoscopy (CTVB) were. Results The shapes of the main airway obstructive diseases were displayed directly in all of the 70 patients using MSCT postprocessing techniques. The percent area stenosis was measured from the MPR images

including 4 mild stenosis (50%)

21 moderate stenosis (50%-75%)

29 severe stenosis (75%)

16 obstructed (100%). The shape

range and degree of main airway obstructive diseases were accurately displayed in MPR images without three dimensional effect. The endoscopic views of stenosis were delineated through CTVB and the three-dimensional images of the pathological changes of main airway obstructive diseases were obtained through VR. Conclusion MPR postprocessing techniques can accurately display the main airway obstructive diseases

therefore it is a useful tool in clinical practice. However

the clinical value of CTVB and VR images is limited.
