Liposomes (size 220 \u00b5g), loaded with clodronate, were injected into the peritoneum of three C57BL\/6 mice. On the third day, 200 \u00b5L of the particulate agent ExiTron nano 6000 were injected into three macrophage-ablative mice and three control mice. CT scans were acquired before and 3 min, 1 h, 6 h, and 24\u2009h after the ExiTron application. The animals were sacrificed, and their spleens and livers removed. Relative CT values (CTV) were measured and analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Liver and spleen enhancement of treated mice and controls were increasing over time.
