To further evaluate the ability of the CCR2 radiotracer to predict AAA wall stress, we used the AAA wall cumulative uptake value (0.53±0.3) within the MAS area as a threshold for high or low signal classification in order to subdivide all AAA patients into two groups (Supplementary Results 6; six high CCR2 patients and four low CCR2 patients). This evidence concerns the gene CCR2 and triple-A syndrome.
