Abstract:
Objective To analyze the selection of puncture needles in CT-guided percutaneous biopsy in musculoskeletal system diseases.Methods Three hundred and sixty-four undiagnosed lesions of musculoskeletal system underwent CT-guided percutaneous biopsy from January 1996 to March 2005.Proper selection of different puncture needles,including biopsy gun,bone biopsy needle,or both,was made according to different locations and characteristics of the lesions.Results Among 255 lytic lesions,the biopsy gun alone was used in 47 cases and both biopsy gun and bone biopsy needle were used in 208 cases.Among 73 mixed lesions,the bone biopsy needle alone was used in 49 cases,biopsy gun alone in 14 cases,and both in 10 cases.The bone biopsy needle was used in all 36 sclerotic lesions.Enough specimens were obtained in all the cases,and no complications occurred.A correct biopsy diagnosis was made in 334 cases,the diagnostic accuracy of biopsy being 91.8%(334/364). Conclusions The puncture needles for CT-guided percutaneous biopsy of the musculoskeletal system lesions should be selected according to different locations and characteristics of lesions.For sclerotic lesions or lesions containing relatively more sclerotic contents,the bone biopsy needle should be used.For lytic lesions,the biopsy gun should be used.And the combined use of both bone needle and biopsy gun should be utilized for mixed lesions.
