title: Chronic osteomyelitis: the relative roles of scintigrams, plain radiographs, and transmission computed tomography.
abstract: We evaluated the relative contribution of transmission computed tomograms (CT), plain radiographs, and bone/gallium scans in the diagnosis of 27 patients with suspected active chronic osteomyelitis. All patients were imaged with all modalities and had surgical proof of the presence or absence of disease. At surgery, osteomyelitis was shown to be active in 20 patients, 15 of whom had sequestra, and inactive in the remaining seven. CT depicted all 15 sequestra, but was falsely positive in three patients, all of whom had bone remodeling only and had negative bone/gallium scintiscans. Plain radiographs had a limited value; they detected sequestra, which was the only findings to indicate the presence of active disease, in 5 patients out of the 15 with surgical proof thereof. The authors conclude that, considering the shortcoming of other modalities with regard to depicting sequestra, scintigraphy is helpful in confirming the presence or absence of active disease and therefore in preventing unnecessary surgery.
