CT引导下穿刺活检术在骨疾患诊断中的应用和准确性分析

Accuracy and utility of CT guided biopsy of bone lesion

[目的]评价CT引导下经皮骨组织穿刺活检术的实用性和对疾病诊治的意义。[方法]对CT引导下骨组织穿刺活检术137例进行总结分析。[结果]病灶刺中率100%,穿刺活检病理结果122例获得明确诊断,15例诊断不明确或误诊。穿刺活检总的诊断准确率89.0%,其中转移癌、原发恶性肿瘤和良性病变诊断准确率分别为95.8%、85.7%和85.1%。[结论]CT引导下经皮骨组织穿刺活检术,创伤小、诊断准确率高、并发症少,是一种安全有效的诊断方法,对指导治疗有重要意义。

[Objective] To evaluate the accuracy and value of CT guided biopsy of bone lesion. [Method] A total of 137 cases of CT guided biopsy were analyzed, including 1 case of cervical vertebrae, 22 cases of thoracic vertebrae, 47 cases of lumbar vertebra, 8 cases of sacrum, 9 cases of pelvis, 2 cases of scapula and 48 cases of extremities. The biopsies were completed in local anesthesia under CT guidance, using trephine needle or Tru-eut needle. [ Result] The puncture accuracy was 100%, the general diagnostic accuracy was 89. 0% （ 122/137）, in which the diagnostic accuracies of metastasis lesion, primary bone tumor and benign lesion were 95. 8% （46/48） , 85.7% （36/42） and 85. 1% （40/47） respectively. [ Conclusion] CT guided biopsy was a safe and accurate method with little trauma and complication, having great value in deciding treatment of bone lesions.
