Influence of dodecafluoropentane emulsion (DDFPe) treatment start time on percent infarct volume at 4 hours. Pre-treat represents DDFPe administration starting 30 minutes before embolization.

DDFPe treatment start time	N	Mean ±Standard Error, %	Median, %	P-value (unadjusted)	P-value (Dunnett-adjusted)

P-values compare each treatment time to untreated controls.
