摘　　要：目的：评价胸部ＣＴ导向穿刺活检中ＣＴ定位、取材方法、病变等因素对本项检查准确性的影响。材料与方法：回顾分析１００例资料完整的病例。分别计算用不同取材方法，对不同部位病灶检查的准确性，分析各因素对准确性的影响。结果：对肺部恶性病变细胞学和组织学诊断的正确率分别是９０％和８７％，对肺部良性病变细胞学和组织学诊断的正确率分别是６０％和８４％。对纵隔和胸膜病变组织学诊断准确性高。结论：细胞学诊断对肺部恶性病变的诊断准确性高，组织学诊断对肺部良性病变的准确性高，对肺部病变应根据影像学诊断决定取材方式。对纵隔、胸膜等处病灶应取得充分的组织学标本方易作出确切诊断。Purpose:To evaluate accuracy of CT-guided, needle biopsy in terms of sampling method and location. Materials and methods: The method and location of the procedure as related to diagnostic accuracy were studied and analyzed retrospectively in 100 cases. Results: For pulmonary malignant lesions, diagnostic accuracy was 90% in cytologic study and 87% in histologic examination, whereas for pulmonary benign lesions, accuracy was 60% and 84% in cytologic and histologic diagnosis respectively. Most mediastinal and pleural lesions were diagnosed correctly only by histologic study. Conclusion: Cytologic diagnosis had higher diagnostic accuracy in pulmonary malignant lesions, while histologic diagnosis was superior to cytology in pulmonary benign lesions. Proper selection of the method of the procedure should be made on the basis of imaging diagnosis. For mediastinal and pleural lesions, adequate specimen for histologic study was mandatory in order to reach a definitive diagnosis.
