FDG PET hot spots spell risk of rupture in abdominal aortic aneurysm

September 10, 2013

A higher risk of aneurysm is on the menu for patients who test positive for abdominal aortic inflammation and other cellular changes, according to a study published online Sept. 5 in the Journal of Nuclear Medicine .

The 13th leading cause of death in Western countries is the rupturing of an abdominal aortic aneurysm (AAA). F-18 FDG uptake in the abdominal aortic is present in a significant number of patients at high risk for rupture. Research scientist Audrey Courtois from the Laboratory of Connective Tissues Biology, GIGA-R at the University of Liege in Sart-Tilman, Belgium, and colleagues found strong inflammatory and other potentially damaging processes in the aortic wall that explained the association.
