Abstract
BACKGROUND AND PURPOSE: Diffusion-weighted imaging (DWI) identifies acute cerebral ischemia and DWI lesions are thought to indicate irreversibly damaged areas. However, new evidence suggests that DWI lesions may be reversible, especially with reperfusion. We present a patient who showed substantial reversal of her acute DWI lesion following partial aortic occlusion with Neuroflo™, a novel dual balloon catheter (Neuroflo™, CoAxia, MN). METHODS: Case report/literature review. RESULTS: A 48-year-old woman presented with left-sided weakness and demonstrated an acute DWI lesion in the right middle cerebral artery territory, with diffusion-perfusion mismatch. She was enrolled into an experimental study in which a dual balloon catheter was inflated in the lower aorta. The patient improved and her postprocedure magnetic resonance image showed a significant reduction in lesion volume on diffusion and perfusion-weighted imaging. At 1 month, a repeat computed tomography scan showed a small infarction in the right insula, lentiform nucleus, and frontal cortex. The patient had recovered with no significant disability at her 3-month follow-up. CONCLUSION: Reperfusion can improve DWI lesions. Partial aortic obstruction with a novel dual balloon catheter may be useful to promote reperfusion.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
