目得：确定使用20号自动切割活检针的同轴经胸针吸活检（TNB）在胸部病变的诊断中的实用性。材料和方法：对122例患者进行了回顾性分析。使用计算机断层扫描引导同轴TNB，使用抽吸针（n = 87）和自动切割针（n = 99）进行TNB。恶性和良性病变的敏感性进行了测定，从两种techniques.RESULTS：同轴TNB的总体诊断率为88%的相对收益率进行比较。对于恶性肿瘤的敏感性为95%，而一个特定的良性诊断是在91%。恶性病变细针穿刺活检与空芯针穿刺活检的阳性率无差异（92%比86%），但良性病变细针穿刺活检与空芯针穿刺活检的阳性率有显著差异（44%比100%，P
PURPOSE: To determine the utility of coaxial transthoracic needle biopsy (TNB) with use of a 20-gauge automated cutting biopsy needle in the diagnosis of thoracic lesions.MATERIALS AND METHODS: A retrospective review was performed in 122 patients. Computed tomography was used to guide coaxial TNB, which was performed with aspirating (n = 87) and automated cutting (n = 99) needles. The sensitivities for malignant and benign lesions were determined, with a comparison of the relative yields from the two techniques.RESULTS: The overall diagnostic yield for coaxial TNB was 88%. For malignancy the sensitivity was 95%, whereas a specific benign diagnosis was obtained in 91%. Although no difference was found for fine-needle aspiration versus core biopsy of malignant lesions (92% vs 86%), a statistically significant difference was found for benign lesions (44% vs 100%, P
