Paper Abstract

Stereotactic radiofrequency (RF)-lesioning in the central part of the brain is performed on patients that, for instance, have severe movement or psychiatric disorders. The size of the generated lesion can to some extent be controlled by RF-generator settings such as temperature and time as well as the electrode configuration. Today, MR- imaging and CT are the essential diagnostic methods to confirm the lesion size in vivo. The aim of this study was to investigate whether it is possible to use changes in the reflected light intensity and laser Doppler flowmetry as a marker for size estimation during RF-lesioning.
