Abstract:
:Technetium-99m gamma camera images of kidneys produced with an iodine-131 energy window showed "ghosts" over and between the kidneys and between the kidneys and the bladder. The cause was coincidence summing at 281 keV due to a high 99mTc counting rate. In older model cameras careful peaking with a proper energy window reduces this effect; more recently developed cameras with pileup rejection circuits do not have this problem.
