Aortic 18F-fluorodeoxyglucose (FDG) uptake from PET/CT scans could flag sustained inflammation in patients with surgically repaired coarctation of aorta late during adult life, in the absence of risk factors for coronary artery disease. Increased 18F-FDG uptake in the aorta can be  a novel biomarker predictive of aortopathy or hypertension development at a later stage in these subjects.

Aortic 18F-fluorodeoxyglucose (18F-FDG) uptake by positron emission tomography/computed tomographic (PET/CT) imaging in adult patients with repaired coarctation of aorta (RCoA) and control subjects. Representative PET/CT images of aortic 18F-FDG uptake from axial (A) and coronal (B) views in RCoA and control subjects. White arrows demonstrate areas of increased aortic 18F-FDG uptake. Global aortic 18F-FDG uptake was significantly increased in RCoA compared with control subjects.
