Artifacts in iodine-131 renal images due to coincidence summing of technetium-99m photons

Description

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 /sup 99m/Tc 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
