| 目的 评价C臂CT引导下骨占位病变穿刺活检的临床价值。 方法 回顾性分析2009年10月-2019年5月10年间，283例患者采用C臂CT引导穿刺活检的临床资料。分析技术成功率、诊断灵敏度、特异度、准确度、并发症、辐射剂量等。 结果 C臂CT虚拟导航下骨肿瘤穿刺活检技术成功率100％，平均总手术时间14.10±5.95 min，平均辐射剂量11.21±4.12mSv。3例（1.06％）发生轻微出血。80例（28.26%）术后出现轻度疼痛。在经皮穿刺活检诊断为恶性疾病的患者中，将活检结果与术后明确的组织学诊断结果进行比较，确定经皮穿刺活检诊断的灵敏度为90.82%，特异度为86.96%。 结论 C臂CT 系统融合了DSA 实时透视和螺旋CT精确显像优势，缩短了定位穿刺时间，能够满足骨骼穿刺活检的需要, 值得临床推广使用。 |

| Objective To evaluate the clinical value of C-arm guided CT guided bone biopsy. Methods A retrospective analysis of clinical data from 283 patients with bone-occupying patients who underwent C-arm CT guided biopsy from October 2009 to May 2019. Analyze technical success rate, diagnostic sensitivity, specificity, accuracy, complications, radiation dose, etc. Results The success rate of bone tumor biopsy under C-arm CT virtual navigation was 100%, the average total operation time was 14.10±5.95 min, and the average radiation dose was 11.21±4.12 mSv. Minor bleeding occurred in 3 cases (1.06%). Mild pain occurred in 80 patients (28.26%). In patients diagnosed with malignant disease by percutaneous biopsy, the biopsy results were compared with postoperatively confirmed histological diagnosis, and the sensitivity of the percutaneous biopsy was 90.82% and the specificity was 86.96%. Conclusion The C-arm CT system combines the advantages of DSA real-time fluoroscopy and spiral CT for precise imaging, shortens the positioning puncture time, and can meet the needs of bone biopsy. It is worthy of clinical promotion. |
