Imaging the urinary pathways in mice by liposomal indocyanine green

Free and liposomal ICG distribution ex vivo(A, B) and in vivo(C) by NIR optical imaging. Arrows indicate ureters (A, B) and bladder (C). Tissues were imaged 10 min after intravenous injection of 8 mg/kg ICG. Mice were imaged approximately 20 min after ICG injection.135
