Fluoroscopy-Guided Percutaneous Vertebral Body Biopsy Using a Novel Drill-Powered Device: Technical Case Series

Abstract

A drill-assisted, coaxial biopsy system can be used to safely obtain vertebral body core specimens under fluoroscopic guidance. The higher bone core yield obtained with drill assistance may be offset by the presence of crush artifact.

Diagnostic Accuracy and Adequacy of Computed Tomography Versus Fluoroscopy-Guided Percutaneous Transpedicular Biopsy of Spinal Lesions

“…Our study finds that the accuracy of spinal biopsy is 83.3%, which is consistent with other studies with an accuracy of spinal biopsy ranging from 16.1% to 92.7% [3,[6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Fluoroscopy-guided spinal biopsy has higher accuracy compared to CT-guided biopsy (86.6% vs. 80%), but it is not statistically significant (p = 0.731).…”

“…The radiation exposure to the operating personnel is 26 times higher in the CT-guided group compared to the fluoroscopy-guided group [3]. Despite the poorer spatial resolution, fluoroscopy-guided biopsy of spinal lesions has been proven to be a feasible alternative to CT-guided biopsy [3,[11][12][13]. Nevertheless, there is limited literature from developing countries that compare the two methods of biopsy.…”

Evaluating bone biopsy quality by technique in an animal model

“…Accuracy of pathologic analysis of bone specimens can be impacted by artifacts and alterations incurred during the biopsy procedure. While some studies suggest that a rotary-powered device yields a cohesive sample with rare exceptions [2] , [3] , [4] , other studies caution that drill-assisted devices can contribute to crush artifact and shorter lengths of assessable marrow [5] , [6] , [7] , [8] . Operators of the powered system have voiced anecdotal concerns over thermal artifact or burn related to friction, however several studies assessing specimen artifacts did not identify thermal damage [ 5 , 9 , 10 ].…”

CT-guided percutaneous skull biopsy using a drill-assisted system: Technical report of two cases

“…Though initially designed and marketed for bone marrow biopsy, clinical applications have expanded to include percutaneous computed tomography (CT)-guided biopsy of the spine and appendicular skeleton. 3,4 Herein, we report the use of this novel device to perform two CT-guided percutaneous skull biopsies.…”
