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.
原理与目的
提出一种三维立体定向技术，以改进经皮诊断和治疗操作中精确的针放置。
方法
该方法使用横轴位计算机断层扫描（CT）成像来选择最佳目标路径，并采用一种三维立体定向装置，设计用于在三维空间中精确匹配CT参数。
结果
在选定的病例中，我们能够到达小至1至2厘米的目标，同时避开重要结构。
结论
在我们手中，在选定的病例中，这是一种在CT引导下改进经皮诊断和治疗操作的简单、安全且准确的技术。
