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.
