The BSC of SPIO cores that are aggregated in the lysosomes of Kupffer cells is significantly higher (85 dB) than the BSC of non- aggregated SPIO cores. Considering in vivo concentrations, the aggregated SPIO does not elevate the BSC of the liver markedly (9x10-6 dB). Thus, the reported visibility of SPIO in clinical ultrasound cannot be explained by classical scattering theory. Other non-linear effects need to be taken into account. Afiliacje autorów:
