CT-guided Percutaneous Biopsy of Musculoskeletal Lesions:102 Cases Report

Objective: To evaluate the clinical applications and role of CT-guided percutaneous biopsy in musculoskeletal lesions.Methods: A total of 102 musculoskeletal lesion cases underwent 2-or 3-point CT-guided percutaneous biopsy,including 45 cases of soft tissue lesions and 57 cases of bone lesions.All cases were identified pathologically by surgery,open biopsy or had clinical follow-up information.Results: The accuracy of CT-guided percutaneous biopsy was 83.3%(85/102).The accurate rate for soft tissue and bone biopsies was 95.6%(43/45) and 71.9%(41/57) respectively,and that for the bone plus soft tissue biopsy was 95.0%(38/40).Significant differences were found in accurate rates by different biopsy in bone and soft tissue(P0.05).Significant differences in accurate rate for big lesions(diameter3 cm) 88.7%(55/62) and small lesions(diameter≤3 cm) 75.0%(30/40) were found(P0.05).Conclusion: CT-guided percutaneous biopsy is a safe,simple and effective method for the diagnosis and differential diagnosis of musculoskeletal lesions,the big lesion biopsy is superior to the small one,and multipoints or multi-tissues biopsy has a higher accurate rate.
