ABSTRACT
OBJECTIVES: To demonstrate that inflammatory atheromatose carotid plaques can be visualized with positron emission tomography with 18F-fluorodeoxyglucose (18FDG PET) in symptomatic patients, in order to correlate them with systemic inflammatory markers, such as CRP. METHOD: Fifteen patients with cerebral ischemia due to atherosclerotic carotid disease were studied. 18FDG uptake with PET was considered and blood samples were taken for determining high sensibility C reactive protein (HsCRP). RESULTS: The mean age of the patients was 66 years; 11 of them were males (73%) and 4 were females (27%). 18FDG PET was positive in 12 patients (80%), while 100% of the studied population had low risk HsCRP with normal white cell count. CONCLUSIONS: 18FDG PET proves active inflammation in carotid atheromatose plaques. There was no significant correlation between the presence of ahteromatose carotid plaques, HsCRP serum levels, and 18FDG PET study.
