Current Challenges In Imaging Of The Diabetic Foot

Abstract

Although a variety of diagnostic imaging modalities are available for the evaluation of diabetes-related foot complications, the distinction between neuroarthropathy and osteomyelitis is still challenging. The early and accurate diagnosis of diabetic foot complications can help reduce the incidence of infection-related morbidities, the need for and duration of hospitalization, and the incidence of major limb amputation. Conventional radiography, computed tomography, nuclear medicine scintigraphy, magnetic resonance imaging, ultrasonography, and positron emission tomography are the main procedures currently in use for the evaluation of diabetes-related foot complications. However, each of these modalities does not provide enough information alone and a multimodal approach should be used for an accurate diagnosis. The present study is a review of the current concepts in imaging of diabetes-related foot complications and an analysis of the advantages and disadvantages of each method.
