Microvascular Injury and Perfusion Changes Induced by Ultrasound and Microbubbles in a Machine-Perfused Pig Liver
Keravnou, Christina P.; Cock, Ine De; Lentacker, Ine; Izamis, Maria-Louisa; AVERKIOU, MICHALAKIS A. (2016)Localized drug delivery and uptake can benefit from the combined action of ultrasound and microbubbles at a specific site. Some of the possible mechanisms suggested are vessel poration and/or cell poration, but the exact ...
