title: False-positive studies in early 67Ga-citrate scintigraphy.
abstract: Two cases of false-positive early 67Ga-citrate scintigraphs are presented. In both cases, the initial accumulation of the radiotracer in the region of the right iliac fossa could not be substantiated on the delayed study. It is suggested that the results of an early gallium scan be interpretated cautiously, especially when any apparent abnormality is within the region of the normal colonic anatomy. A delayed study should be performed whenever possible.
