Clinical Molecular Imaging of Chemokine Receptor CXCR4 Expression in Atherosclerotic Plaque Using 68Ga-Pentixafor PET: Correlation with Cardiovascular Risk Factors and Calcified Plaque Burden

Conclusion: 68Ga-pentixafor PET/CT is suitable for noninvasive, highly specific PET imaging of CXCR4 expression in the atherosclerotic arterial wall. Arterial wall 68Ga-pentixafor uptake is significantly associated with surrogate markers of atherosclerosis and is linked to the presence of cardiovascular risk factors. 68Ga-pentixafor signal is higher in patients with a high-risk profile and may hold promise for identification of vulnerable plaque.
