Value of CT-guided Percutaneous Biopsy for the Spine Lesions

Objective To explore the technology and diagnostic value of CT-guided percutaneous biopsy for the spine lesions.Materials and Methods Sixty-two cases of patients(45 male,17 female) with the spine lesion underwent CT-guided percutaneous biopsy.The spinal lesions involved single vertebra in 38 cases,two vertebrae in 14 cases,and multiple vertebral in 10 cases.The localization of lesions were cervical vertebra in 2 cases,thoracic vertebra in 28 cases,lumbar vertebra in 25 and sacral vertebra in 7 cases.Precise needle paths were designed according to CT images.The biopsy specimens were further histologically examed.Results Adequate specimens for pathologic examination were obtained in 52 of 62 cases (80.8%).The remaining 10 cases included no specimen be obtained(6 cases),uncertainty pathological diagnosis (3 cases) and discordancy(1 cases).Clear histological diagnosis was obtained after i mmunohistochemistry examination in 10 cases.Conclusion CT guided pereutaneous biopsy is a minimally invasive,safe and reliable tool in the evaluation of spinal lesions.
