Early static acquisition: timing, FOVs time per FOV
5–10 min p.i. static acquisition of the pelvis (1 FOV of 4 min)
60 min p.i. wb scan from the orbitomeatal level to the superior portion of the thighs (6-7 FOVs, 3 min/FOV)
Low dose CT no contrast
6-hour fasting and 1-hour avoidance of liquids to reduce bladder filling before tracer injection. Voiding was requested immediately before scanning to minimize the presence of tracer in the urinary tract.
Tracer injection after the CT scan. 10 min list-mode acquisition on the prostate bed starting immediately with the tracer injection generating -min time frames corresponding to 0 to 3 min, 3 to 6 min, and 6 to 9 min after injection.
10 min after injection standard wb 7-8 FOVs, 3-4 min/FOV each depending on patient size and weight.
Two additional late images of 5 min each of the pelvis immediately after the wb PET scan (about 45 min after tracer injection).
Low dose CT
Fasting for at least 4 hours before the FCH. Empty bladder on scanning.
