目的：探讨C臂CT在胸部病变穿刺活检中的准确性、安全性及临床应用价值。方法：整理我院介入科2018年2—12月共243例胸部病变C臂CT引导经皮穿刺活检的临床资料，分析评价技术成功率、诊断准确率、敏感度、特异度及并发症发生率。结果：243例患者共行经皮穿刺活检249次，6例先后行2次活检，技术成功率100%，并发症发生率12.76%。48例接受外科手术治疗，总的诊断准确率97.92%（47/48），敏感度97.73%（43/44），特异度100%（4/4）。结论：C臂CT结合了DSA透视和CT两种影像技术的优点，优化了胸部肿瘤穿刺活检的工作流程，使得其在引导胸部肿瘤经皮穿刺活检中具有明显的优势，具有准确度高、并发症少等技术特点，引导穿刺更加安全、可靠，值得临床推广、应用。
Abstract
Objective: To explore clinical application, safety and exactitude of C-arm CT-guided percutaneous lung biopsy in the diagnosis of chest tumor. Methods: The clinical data of 243 cases with C-arm CT-guided percutaneous lung biopsy from February to December 2018 were analyzed respectively. Including technical success rate, accuracy, sensibility, specificity, and the incidence of complications. Results: A total of 249 percutaneous biopsies were performed in 243 cases, 6 cases biopsies were performed for two times, and the technical success was 100%, the incidence of complications was 12.7%. 48 cases accepted surgical operation. Totally diagnostic accuracy was 97.92%(47/48), sensibility was 97.73%(43/44), specificity was 100%(4/4). Conclusion: C-arm CT combines advantages DSA and CT imaging techniques, optimizing the flow of lung biopsy, it has obvious advantages in percutaneous lung biopsy, and has the technical characteristics such as high accuracy and fewer the incidence of complications. C-arm CT-guided percutaneous lung biopsy is safe and reliable. It is worthy of application and promotion.
