Vascular inflammation is a key factor in both the pathogenesis and outcome of atherosclerosis. Renal insufficiency is close correlation with atherosclerosis and cardiovascular mortality.

18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) is a promising tool for identifying and quantifying vascular inflammation within atherosclerotic plaques.Therefore, the purpose of the study is to demonstrate the correlation between eGFR and vascular inflammation detected by 18F FDG-PET.

Inclusion Criteria:

1. absence of prior cancer diagnosis or remission from cancer at the time of PET imaging and throughout the follow-up period;
2. >=30 years of age;
3. no prior history of cardiovascular disease ; and
4. absence of acute or chronic inflammatory or autoimmune disease (based on documented medical history) or use of chronic anti-inflammatory therapy.

Exclusion Criteria:

1. age <35 years
2. presence of chronic inflammatory disease
3. use of anti-inflammatory medications
4. presence of active malignant cancer (defined as any radiological or pathological evidence of malignant cancer disease or undergoing chemotherapy or radiation therapy within 1 year before initial PET/CT and throughout the inter-scan duration).
