Fig 7. SUVmax values of [11C]acetate PET/CT and [18F]florbetapir PET/CT.
On the early images (2–6 minutes after injection of radiotracer), subjects with intense visual lung uptake of [18F]florbetapir had significantly higher [18F]florbetapir SUVmax values than subjects with no uptake (1.5, IQR 1.1–3.2, vs 12.8, IQR 9.4–18.0, p<0.001) but the median [11C]acetate SUVmax of the lungs were similar in all subjects (1.1, IQR 0.8–1.7, vs. 1.4, IQR 0.8–1.6, p=0.959), suggesting pulmonary AL amyloidosis. The median is shown. Each marker corresponds with a single subject
