The role of high quality DTI is clearly highlighted in this preliminary evaluation, to more accurately identify the initial target for sonication in MRgFUS presurgical planning.
Figure2:
Top row: coronal view of the acute postsurgical T2WI from four patients where
final target has been identified (blue dot), based on the criteria described in
figure1. Bottom row: coronal view of the high quality presurgical DTI and the
corresponding location of the final target, for each patient.
Figure3:
Left column: In patient 3, the location of the first target point of
sonification on postsurgical T2WI and its corresponding location on the high quality
DTI. The sub threshold initial sonication at this site resulted in patient experiencing slight paresthesia. Right column: The final target location selected for surgery based on
the positive functional feedback received from the patient and its corresponding
location on the presurgical high quality DTI.
