Correlation of FDG PET/CT Findings with Long-Term Growth and Clinical Course of Abdominal Aortic Aneurysm

a Measurement method for AAA. An ellipsoidal VOI was placed over the abdominal aorta including all lesions of the AAA, excluding the anatomical structures of physiological uptake (red circle). Maximal SUV of the AAA was obtained from this VOI. b Measurement method for the SVC. ROIs were drawn manually on each slice of the PET/CT image to cover the SVC from the root of the brachiocephalic vein to the cavo-atrial junction to make a stacked VOI (yellow contour). Mean SUV was obtained from this VO
