Percutaneous CT-guided biopsy: improved confirmation of sampling site and needle positioning using a multistep technique at CT fluoroscopy

S N Goldberg et al. J Comput Assist Tomogr. 2000 Mar-Apr.

Abstract

We describe a new multistep procedure for CT fluoroscopy-guided core biopsy, which allows confirmation of the biopsy-sampling trough and the final needle tip position prior to sampling. Twelve lesions measuring < or =2 cm or in close proximity to vital structures were biopsied using commercially available biopsy systems. Diagnostic biopsies were obtained in all cases. Mean fluoroscopy time was 11.1 +/- 2.8 s per biopsy. This technique may have the potential to improve the accuracy and safety of CT-guided biopsy.
