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,(More)
The right tibias of sixty-six rabbits were injected with a suspension of Staphylococcus aureus and sodium morrhuate. After four weeks, 43 rabbits developed osteomyelitis and were started on a course of antibiotics. During treatment a gallium-67 scintigram was obtained every two weeks, for up to 10 weeks. During the treatment weeks, 25 rabbits developed(More)
The 17 beta-estradiol-induced increase of uterine blood flow (UBF) was studied in 7- to 8-month-old oophorectomized rabbits 6-39 days after operation. Baseline blood flows were determined with 141Ce-labeled microspheres and 2-h flows with 85Sr-labeled microspheres. Mean UBF in control groups ranged from 0.11-0.26 mi/min . g. Mean UBF 2 h after 17(More)
Twenty rabbits with chronic osteomyelitis of the tibia were treated for eight weeks and then scanned with Tc-99m MDP and Ga-67 citrate. All were sacrificed and bacteriologic cultures of the tibia were obtained. All rabbits had positive Tc-99m MDP scans at the end of treatment despite thirteen cures of osteomyelitis. Eight had negative gallium scans and(More)
A variety of shoulder injuries have been well described in the overhead-throwing athlete, including internal and external impingement, instability, labral derangement, biceps pathology, and rotator cuff dysfunction. However, injury to the muscles of the posterior shoulder, in particular the latissimus dorsi and teres major, occur much less frequently and(More)
