Aims and objectives: to compare the effectiveness of radiological methods for the establishment of osteomyelitis (OM) in the diabetic foot (DF).

Methods and materials: 85 patients (41 male (48.2%), 44 female (51.8%); mean age 59.4±7.1) with suspected diabetic foot bone infections were studied.  The study included patients with neuropathic (n = 25), ischemic (n = 13) and neuroischemic (n = 47) DFS forms. Fusions of SPECT and MRI or CT were performed in pr[...]

Results: Values of sensitivity, specificity and accuracy of X-ray and CT were 76.3%, 44.7%, 58.8% and 81.6%, 63.8%, 71.8% respectively. Low specificity of X-ray and CT was principally due to false positive results (FP) in Charcot foot (fig. 1-2). Also it should be noted poor visualization of soft tissues. Va[...]

Conclusion: Among the available methods of radiological diagnosis of osteomyelitis in the diabetic foot, priority is given SPECT/MRI or SPECT/CT. But SPECT-WBC/MRI has potentially advantage in the indication of soft tissue infections.
