摘　　要：目的 :评价CT仿真支气管镜 (CTVB)对中心气道病变的诊断价值 ,并初步总结CTVB对中心气道病变的诊断依据。材料和方法 :40例临床症状为咳嗽、胸痛或咳痰带血的患者行螺旋CT扫描、CTVB成像和FOB检查后 ,比较CT和FOB之诊断结果。结果 :CTVB对 40个病例中的 3 8个中心气道病变作出了与FOB所见相符的正确描述。CTVB能穿过 9处严重狭窄的支气管观察远端支气管的改变 ,而FOB不能。结论 :CTVB是一种无创无痛苦检查中心气道的新方法 ,其与传统横断面CT结合有助于对中心型肺癌准确分期 ,其对中心型肺癌放疗、化疗及手术后的随访观察可基本取代FOB。Purpose:To evaluate the value of CTVB in diagnosing the lesions of central airways and its diagnostic basis.Materials and Methods:Forty patients with disorder symptoms in respiratory system were examined with CTVB and FOB. We compared the diagnosis of central airways lesions by CTVB and FOB. Results:38 of 40 patients were diagnosed correctly by CTVB and coincided with those of FOB. CTVB offered the advantage of being able to visualize areas beyond even high grade stenosis in nine patients.Conclusion:CTVB is a new noninvasive method for evaluating the lesions of central airways. CTVB combined with cross sectional images can evaluate the stage of tumors in the central airways and may displace FOB in evaluating the patients treated by radiotherapy, chemotherapy and operation.
