Figure 3:11C-acetate PET/CT (patient no. 6) showing transverse sections of 1st (5min.), 2nd (20 min.) and a delayed 3rd run (45 min.) after tracer injection. The 1st and 2nd run showed suspicious and equivocal interpretation of a lesion in the left posterior lobe, respectively (solid line arrow, ←). The 3rd run and the global reading were judged as negative. The SUVmax over the 3 runs were 4.4, 3.7 and 2.4.
