CT导向穿刺活检在骨骼病变诊断中的价值

目的探讨CT导引活检在骨骼病变的临床应用价值.方法对52例骨骼病变行CT导引下活检,每例常规取材2～3次.29例病灶区或灶周硬化明显者应用了Ackermann骨钻针,17例骨质破坏明显者应用了核心切割针,6例囊性或有明显液化区的病灶则细抽吸针.结果活检的诊断准确率90.4%(47/52).5例假阴性者包括2例增生硬化性病灶,3例液化性.结论 CT导引下骨骼活检是诊断骨病变重要手段,是一种安全、准确而有效的方法,对临床治疗决策具有重要的指导价值.

Value of bone puncture biopsy under CT guidance in diagnosis of bone diseases

Objective To evaluate the value of percutaneous bone puncture biopsy under CT guidance in bone diseases. Methods Percutaneous bone puncture biopsy was performed under the guidance of Siemens Somatom Plus 4 CT in 52 cases. The tissues in each case were collected routinely for 2 or 3 times. Ackermann needle, core cutting needle, and fine suction needle were used in 29 cases with obvious lesions or sclerotic lesions, 17 cases with obvious destruction of bone, and 6 cases with cystic lesions or lesions with obvious liquefied areas, respectively. Results Histopathological diagnosis was obtained in 47 patients. The accuracy of biopsy was 90.4%. The specimen was false-negative in 5 patients, including 2 cases of sclerotic lesion and 3 cases of liquefied lesion. Conclusion Percutaneous bone puncture biopsy, a safe, reliable, and important method for the diagnosis of bone lesions, is of great significance in clinical therapeutic decision-making.
