A comparison between magnetic resonance imaging and scintigraphic bone imaging in the diagnosis of disc space infection in an animal model.


In a controlled prospective study, 33 rabbits were used to compare the efficacy of magnetic resonance imaging (MRI) to scintigraphy in diagnosing pyogenic infection of the intervertebral disc. A suitable inoculum of Staphylococcus aureus (10(8) organisms) was injected into a test level while a similar volume of sterile culture medium was injected into a… (More)
