Magnetic resonance imaging–guided focused ultrasound thalamotomy for an essential tremor patient with a subcutaneous implantable cardioverter defibrillator: A case report
Bibliographic record
Abstract
Abstract We report a 52 years‐old, right‐handed man with medication‐refractory essential tremor (ET). Because of ventricular fibrillation (Vf) due to coronary spasm, he had been treated with an MR‐conditional subcutaneous implantable cardioverter defibrillator (S‐ICD) and medications including amiodarone, nifedipine, and isosorbide nitrate. Amiodarone was discontinued as Vf was not observed for more than 2 years, and it induced thyrotoxicosis. Vf did not occur after the cessation of amiodarone. Moreover, he did not suffer from an angina attack after the administration of vasodilators. After receiving informed consent to stop S‐ICD during the procedure, we performed MRI‐guided focused ultrasound (MRgFUS) left ventral intermediate nucleus thalamotomy. The right‐hand tremor disappeared immediately, and we observed neither Vf nor S‐ICD‐related complications during the procedure. MRgFUS thalamotomy may be feasible as one of the therapeutic options for ET patients even with S‐ICD.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
