目的探讨多层螺旋CT多平面重组(MPR)重建对中央气道占位的CT诊断价值和对治疗的指导意义.方法对9例中央气道占位的病例进行多层螺旋CT扫描,在工作站上进行MPR重建处理,分别对轴位图像和重建图像进行分析对比.结果 MSCT对于6例中央气道肿瘤及3例异物的病例进行横断薄层扫描及MPR重建后分析得出,MPR重建能明确显示中央气道,气道占位部位、大小、管腔狭窄程度、截断,管壁增厚及管周改变.结论多层螺旋CT MPR重建功能能够有效地评价中央气道病变的解剖与病理关系,有助于气管占位的诊断与鉴别诊断,并指导治疗.

Objective To investigate the diagnostic value and directing significance in treatment of MSCT, MPR reconstruct for the lesion in central airway. Methods MSCT was performed on 9 patients with lesion in central airway. The images were reconstructed with MPR on the workstation, then the axial images and the reconstruction images were compared and analyzed. Results MPR reconstruct can reveal explicity the structure of central airway, postion and size of lesion, degree of lumen narrow, truncation,proliferation of trachea and change of exterior central airway. Afert the analysis for 6 cases of tumor in the central airway and 3 cases of Foreign body in trachea. Conclusions Spiral CT, MPR can evaluate the relation of anatomy and pathology for central airway, it is a useful techniquer for diagnosis and differentialdiagnosis for the lesion in the central airway, moreover it can guide the treatment.
