This investigation examined the vascular 18F-FDG uptake by PET/CT and its correlation with circulating MMP-1 levels. Methods: We examined 25 consecutive patientswith significant carotid stenosis and 22 healthy control subjects using 18F-FDG PET/CT. The leukocyte counts, C-reactive protein (CRP), and MMP-1 were measured. Results: 18F-FDG arterial uptake, as well as calcifications, was significantly higher in extensive distributions in patients with established carotid stenosis. However, their distribution was not consistently overlapping. The values of circulating MMP-1 and leukocyte counts were significantly higher in patients with carotid stenosis (all P < 0.05). In addition, subjects with higher 18F-FDG uptake (maximum SUV > 2.0) in target lesions had higher baseline and poststenting MMP-1 levels (all P < 0.05). Conclusion: We provide a link between 18F-FDG uptake and circulating MMP-1. 18F-FDG PET/CT could be used as an adjunct to the clinical management of high-risk atherosclerosis and an in vivo tool to study plaque biology.
