Key Points

The aim is to investigate the relationship between FLAIR signal changes and stroke onset timing in childhood arterial ischemic stroke.
Analyzed FLAIR signal hyperintensity in children with arterial ischemic stroke.
Compared FLAIR signal timing with documented stroke onset.
Evaluated implications for recanalization therapy effectiveness.
FLAIR signal hyperintensity correlates significantly with time since stroke onset.
Children show similar timing of FLAIR signal change compared to adults.
Findings indicate similar windows for effective treatment interventions.

Implication

This analysis demonstrates that FLAIR signals estimate stroke timing in childhood stroke, suggesting similar treatment windows as adults.

Abstract

FLAIR signal hyperintensity can be used to estimate time since stroke ictus in childhood stroke. Children may have a similar FLAIR signal change timing compared with adults, suggesting that they may have a similar window for effective recanalization therapies.
