title: Diminished uptake of 67Ga-citrate in a case of pseudarthrosis.
abstract: A 22-year-old man with pseudarthrosis and infection of the right hip was referred for a 67Ga-citrate scan. A striking decrease was seen in normal bone and soft-tissue uptake in the entire right leg compared with the normal limb. Aortic injection of 99mTc-labeled microspheres showed increased trapping in the region of the hip but contrast angiography was unremarkable. Despite clinical imporvement, 67Ga uptake by the right leg on a repeat scan did not return to normal. This case represents the first report of a "photon-deficient" body part on 67Ga scanning.
