影像学检查对肺内结节性病灶的定性诊断价值有限,CT引导下经皮穿刺活检可有效提高诊断准确性并确定病变的组织来源[1-2]。经皮肺穿刺活检对于肺部结节的诊断价值可高达90%,然而对于难以定性的肺部小结节(≤1 cm)穿刺活检诊断准确性分析,却少有相关文献报道[3]。本研究对98例影响肺部小结节(≤1 cm)穿刺诊断结果的相关因素进行了统计学分析,旨在为提高肺部小结节穿刺诊断结果准确
Imaging diagnosis of nodular pulmonary lesions qualitative diagnosis is limited, CT guided percutaneous biopsy can effectively improve the diagnostic accuracy and to determine the source of tissue lesions [1-2]. The diagnostic value of percutaneous pulmonary biopsy for pulmonary nodules can be as high as 90%. However, the accuracy of biopsy diagnosis of difficult pulmonary nodules (≤1 cm) is poorly documented [3]. In this study, 98 cases of pulmonary nodules (≤ 1 cm) puncture the diagnosis of the relevant factors were statistically analyzed to improve the diagnosis of small pulmonary nodules puncture results accurate
