How low-field portable MRI can help in acute stroke

Portable low-field MRI is emerging as a clinically relevant adjunct for acute stroke when conventional imaging is unavailable or delayed, supporting stroke-type classification, tissue-based triage in wake-up stroke, and serial post-intervention assessment.

• Advances in hardware and reconstruction have improved low-field image quality for point-of-care use in the ED, ICU, and resource-limited settings.
• Low-field MRI should be deployed as an adjunct, not a substitute, to established CT/angiography pathways in time-critical scenarios.
