摘　　要：目的分析影响MSCT引导下经皮穿刺切割活检准确率的可能因素。方法回顾性分析300例有手术病理或临床及影像学随访结果、MSCT引导下经皮穿刺切割活检患者资料,将患者分为符合组和不符合组,对影响穿刺活检准确率的因素行统计学分析。结果 300例穿刺活检总准确率86.33%(259/300),术后并发症发生率6.67%(20/300)。两组病变大小、分布类型、病变内有无大量坏死或较大空洞、肺部病变周围是否合并阻塞性实变或不张)差异均有统计学意义(P均<0.05),病变的良恶性对穿刺活检准确率的影响差异无统计学意义(P>0.05)。结论影响MSCT引导下经皮穿刺切割活检准确率的可能因素有病变大小、分布类型、病变内有无大量坏死或较大空洞、肺部病变是否合并阻塞性实变或不张。Objective To analyze the possible factors of influencing accuracy of MSCT-guided percutaneous automated cutting needle biopsy.Methods Thirty hundred cases with surgical pathology or clinical and radiographic follow-up results of MSCT-guided percutaneous automated cutting needle biopsy were retrospectively enrolled.All patients were divided into coincidence group and incoincidence group.A various possible factors affecting accuracy of the biopsy were analyzed statistically.Results Biopsy accuracy rate of 300 cases was 86.33%（259/300）,incidence of complications was 6.67%（20/300）.Lesion size,distribution types,with or without a large necrotic lesions or larger voids,whether surrounding merger of obstructive atelectasis of lung on biopsy accuracy rate was statistically significant between both groups（all P〈0.05）,benign and malignant lesions had no influence on the accuracy of biopsy（P〉0.05）.Conclusion The possible factors affecting accuracy of the biopsy are lesion size,distribution types,with or without large necrotic or larger voids,whether surrounding merger of obstructive atelectasis of lung.
