Abstract The monitoring of local vascular kinetics after injection of autologous radiolabelled low-density lipoprotein (LDL) allows characterization of human atherosclerotic lesions as to the presence of foam cells and the quality of endothelial coverage. The following evidence exists: (1) dynamic imaging reveals two types of visual LDL accumulation in the vascular bed, one increasing, becoming visible sometimes only as late as after 24 h, and the other one appearing very early on, but decreasing with time; (2) the accumulation of iodine-123 LDL or iodine-131 LDL in the vascular bed shows three major types of local kinetic curves, which correlate with scintigraphic findings; (3) the accumulation of radiolabelled LDL in the vascular bed of humans in vivo is similar to its uptake in de- and re-endothelialized vessels of experimental animals using 125I-LDL; (4) morphological control in endarteriectomy samples confirms the hypothesis that this promising new approach may for the first time allow the in vivo monitoring of preclinical lesions in humans.
