CT-guided stereotaxis using a modified conventional stereotaxic frame.

Computed tomographic (CT)-guided stereotaxic procedure have become established in a few major centers but a single optimal system has not yet emerged. At Duke University Medical Center, availability of a stereotaxic frame with design features that lend themselves to CT adaptation made modification of this unit, rather than construction of a new dedicated frame, cost-effective. As other centers may seek to modify available stereotaxic equipment in a similar way, this report documents the modifications ans the early clinical experience in four patients in whom CT-guided stereotaxic biopsy procedures were performed.
