Promise and challenges in high acuity brain imaging

Promise	Challenges
Low‐field MRI can assess stoke with relatively high sensitivity and specificity. Automated diagnostic tools are being integrated into portable MRI workflow. Portability could enable mobile stroke units equipped with MRI.	DWI sequences have lower quality on portable scanners. Assessment of stroke penumbra and vasculature remains uncertain. Reading low‐field scans may require retraining for neuroradiology personnel.
