Use of intraoperative stimulation in the selection of target sites for CT-guided stereotactic biopsies.
We have utilized intraoperative stimulation to establish the functional nature of tissue to be biopsied in 20 patients undergoing CT-guided stereotactic biopsies. We have performed from 1-4 stimulations at 2-100 Hz using a monopolar and/or bipolar electrode at the intended target sites. Thresholds for motor and sensory response have been obtained. Stimulation results have ranged from sensory changes to tonic/clonic motor activity of the contralateral body and face.
