Recently, a study in 72 lymphoma patients found that [68Ga]Pentixafor PET/MRI was suitable to visualize inflammation within human carotid plaques, with histological evidence for co-localization of CXCR4 and CD68 [48], thereby confirming previous results of chemokine receptor overexpression in macrophage-rich plaques in a rabbit model of atherosclerosis [49]. This evidence concerns the gene CXCR4 and atherosclerosis.
