CT导引下椎体穿刺活检

CT guided vertebral biopsy

目的：评价ＣＴ导引下椎体穿刺活检对诊断的意义和价值。材料与方法：３６例椎体活检，包括颈椎２例、胸椎１１例、腰椎２１例和骶椎２例。活检时病人体位为俯卧位，穿刺针为Ａｃｋｅｒｍａｎｎ针，有时辅以抽吸针。结果：刺中率为１００％，正确率为８８．６％，假阴性为１１．４％。本组未出现并发症。结论：ＣＴ导引下椎体穿刺活检是一种简便、正确率高的诊断和鉴别诊断的有效方法。

Purpose: To evaluate the diagnostic effectiveness of CT guided vertebral biopsy. Materials and methods: Thirty six patients were studied with vertebral biopsy including 2 cervical segment, 11 thoracic segment, 21 lumbar segment and 2 sacral segment. The patients were in prone position and Ackermann needle was used for all patients, sometimes combined with the aspiration needle. Results: The accuracy of needle puncture was 100%. The accuracy of diagnosis was 88.6%, false negative result 11.4%. No severe complications were observed in this series. Conclusion: CT guided vertebral biopsy is a safe, accurate and effective method for diagnosis and differential diagnosis of spinal lesions.
