Scintigraphic detection of osteomyelitis with Tc-99m MDP and Ga-67 citrate: concise communication.
Using both Tc-99m methylene diphosphonate and gallium-67 citrate, images of the lower extremities in New Zealand white rabbits were obtained on sequential days after inoculation of tibias with Staphylococcus aureus. Gallium-67 scintigraphy was positive earlier in the course of infection than Tc-99m MDP scintigraphy. In addition to 4-hr Ga-67 scintigrams, 24-hr and 48-hr scintigrams were obtained, contributing substantially to interpretation. However, 72-hr Ga-67 scintigrams contributed little additional information.
