Brief Summary:

Diabetic foot osteomyelitis is a common and serious complication of diabetes. While the diagnosis of soft tissue infection can be made with simple physical examination in most cases, bone involvement can be harder to diagnose, often requiring medical imaging. In addition to conventional radiological examinations (x-ray and MRI) nuclear medicine procedures can also provide important physiological information in these patients. These procedures include triple phase bone scan combined with Gallium scintigraphy or a combination of labelled leukocyte scintigraphy and bone marrow scintigraphy using sulfur colloid. These procedure, while they provide useful physiological information, are time consuming, generally requiring at least 2 separate image acquisition on separate days, and can be costly.

18F-FDG is a glucose analog that can be used for PET imaging. In addition to its application in oncology, the literature has shown that FDG can be used to investigate a wide variety of inflammatory and infectious conditions, including diabetic foot infections.

The aim of this study is to compare the usefulness of FDG PET imaging versus "conventional" nuclear medicine (either bone scan and Gallium scintigraphy or labelled leukocytes and sulfur colloid scintigraphy) in patient with suspected diabetic foot osteomyelitis.
