Abstract

RATIONALE AND OBJECTIVES. A three-dimensional stereotactic technique is presented as an improvement in precision needle placement for percutaneous diagnostic and therapeutic procedures. METHODS. This method uses transaxial computed tomography (CT) imaging for the selection of the optimal target path, and it employs a three-dimensional stereotactic device designed to match precisely the CT parameters in a three-dimensional space. RESULTS. In selected cases, we reached targets as small as 1 to 2 cm while avoiding vital structures. CONCLUSIONS. In our hands, in selected cases, this has been a simple, safe, and accurate technique for improvement of percutaneous diagnostic and therapeutic procedures under CT guidance.
