Fig. 1From: Utilization of diagnostic ultrasound and intravenous lipid-encapsulated perfluorocarbons in non-invasive targeted cardiovascular therapeuticsVery low MI images of a thrombosed arteriovenous graft when applying intermittent application of DUS high MI impulses during an intravenous infusion of LEP. Small channels that slowly replenish early in therapy (top row at 25–30 min of treatment) eventually become large channels that replenish more rapidly at 30–40 min of therapy.
