Recently, the MR-guided focused ultrasound technology (MRgFUS) offers the possibility to perform subthalamic thermal ablation with reduced risks and optimized accuracy. However, the ability to reliably predict lesion size is still evolving. The goal of this study was to improve the predictability of lesion size by thermal thresholding areas on MR thermometry during treatment procedures.
