Ultra-low-field portable MRI (ULF-pMRI) enables high-quality bedside neuroimaging during ECMO. We aimed to characterize imaging phenotypes of ABI and explore mechanisms underlying lesion distribution across ECMO configurations. Methods: In this multicenter retrospective observational study, adults receiving ECMO who underwent bedside ULF-pMRI at Johns Hopkins University and University of Texas?Houston from Decembe","pubDate":"2026-10-24","url":"https://www.medrxiv.org/content/10.64898/2026.10.21.26366184v1?rss=1"},"indexado":"2026-10-24T15:27:37.789Z"}}
