Fig. 3From: Characterization of passive permeability after low intensity focused ultrasound mediated blood–brain barrier disruption in a preclinical modelMicrobubbles affects tracer accumulation in a dose dependent and size dependent manner: A–C BBB disruption with LIFU shows significantly higher accumulation of dye for a microbubble dose between 40-200uL/kg for AIB, TxRed and Cs Blue respectively. D The accumulation of tracers is size dependent Accumulation C-14 AIB (105 Da) > TxRed(625 Da) > Cs Blue(10kD). (p < 0.01)Back to article page
