“…Computed tomography (CT) has not been widely used in the evaluation of the diabetic foot. In 1979, Kuhn et al reported bone marrow density changes in osteomyelitis [16], and subsequent reports have described the detection of intraosseous gas and fatfluid levels as well as the visualization of sequestra in chronic osteomyelitis [13,20].…”

Fourteen diabetic patients with suspected foot infection and/or neuropathic joint (Charcot Joint) were evaluated with magnetic resonance imaging (MRI) in an attempt to assess the extent of the infection and also to distinguish infection from the changes seen with neuroarthropathy. The majority of patients with infection had more than one site of involvement and the following diagnoses were made by MRI evaluation: osteomyelitis (n = 8), abscess (n = 7), neuropathic joint (n = 5), septic arthritis (n = 4), and tenosynovitis (n = 4). Clinical or surgical/pathological confirmation of the MRI diagnoses was obtained in all but nine sites of infection or cases of neuropathic joint. If the two diagnostic categories of septic arthritis and tenosynovitis are excluded, all but four of the MRI diagnoses were confirmed. A distinctive pattern for neuroarthropathy was identified in five cases, consisting of low signal intensity on T1- and T2-weighted images within the bone marrow space adjacent to the involved joint. We conclude that MRI is a valuable adjunct in the evaluation of the diabetic foot, and that it provides accurate information regarding the presence and extent of infection in this subset of patients. MRI has proven particularly helpful in differentiating neuroarthropathy from osteomyelitis.

“…Inside the osteomyelitis lesions there were colonies of bacteria within the metaphyseal capillary loops, so the present porcine model supports the theory that the pathogenesis of abscess formation in bones involves haematogenous spread. CT scanning has been reported as optimal for detection of small sequestra of devitalized bone tissue (Hernandez, 1985), which are reported to be present in paediatric osteomyelitis lesions after 10 days of infection (Steer and Carapetis, 2004). In the present study, devitalized bone tissue was seen as foci of increased opacity on the CT scans.…”

“…In these cases, the primary role of cross-sectional imaging is staging the infection. For example, CT is useful for surgical planning to identify a sequestrum or foreign body [56]. MRI can also help determine treatment in chronic osteomyelitis [57], by demonstrating non-drained abscesses, and by assessing the viability of the infected bone (by the presence or absence of enhancement after intravenous contrast administration).…”
