Abstract

fetched live from OpenAlex

INTRODUCTION: Real-time monitoring during MR-guided focused ultrasound (MRgFUS) procedures has been considered essential to monitor tremor improvement and side effects in the alignment and/or verify phase before the actual MRgFUS treatment and following the ablative sonications. However, a subgroup of patients does not tolerate being awake during the entire procedure for a variety of reasons. CASE PRESENTATIONS: We performed MRgFUS treatments in three Parkinson's disease/Parkinsonism patients under general anesthesia. These patients had previously failed an attempt to undergo the procedure awake. All 3 patients who had the procedure under general anesthesia experienced significant improvement of their symptoms and experienced only transient adverse effects (e.g., balance problems, left facial droop) that were no longer evident at their first postoperative visit. CONCLUSION: Our findings suggest that MRgFUS treatment under general anesthesia could possibly be done safely and may represent a valid therapeutic option for patients unable to tolerate the procedure awake.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
