Percutaneous biopsies (PB) of the spine under CT guidance have become an important diagnostic tool in managing tumoral or infectious disease of the spine. This retrospective review reports the results of 104 biopsies of the spine, except the cervical spine, performed in 98 patients (66 females and 55 males), aged from 3 to 92 years, without complications. The overall accuracy is 71% but it must be emphasized that the diagnostic accuracy in tumoral lesions is 100% whereas in the case of suspected infectious lesions the accuracy falls to 61.5%. Our view is that the negative results are independent of the technique and we propose a second biopsy before considering a surgical approach. We conclude that this technique is safe, accurate and easy to perform, not only due to the advantages of CT but also to the improvement in biopsy needles and histocytological techniques.
CT引导下经皮脊柱活检已成为脊柱肿瘤或感染性疾病管理中的重要诊断工具。本回顾性研究报告了98例患者（66例女性和55例男性，年龄3至92岁）除颈椎外的104例脊柱活检结果，均无并发症。总体准确率为71%，但必须强调的是，肿瘤性病变的诊断准确率为100%，而疑似感染性病变的准确率降至61.5%。我们认为阴性结果与技术无关，建议在考虑手术治疗前进行二次活检。我们得出结论，该技术安全、准确且易于操作，这不仅得益于CT的优势，还得益于活检针和组织细胞学技术的改进。
