In Vivo Imaging of Abdominal Aortic Aneurysms:Increased FDG Uptake Suggests Inflammation in the Aneurysm Wall

To study the potential of integrated positron emission tomography and computed tomography (PET/CT) to identify aneurysm wall inflammation.The level of F18-fluorodeoxyglucose (FDG) uptake was studied in aneurysmal and normal-sized aortas of 34 male patients [17 with abdominal aortic aneurysm (AAA) and 17 age-matched controls] identified in a database of 278 consecutive patients evaluated for staging of primary lung cancer. The maximal...
