ACR Appropriateness Criteria on suspected osteomyelitis in patients with diabetes mellitus.

Abstract

Imaging of the diabetic foot is among the most challenging areas of radiology. The authors present a consensus of the suggested tests in several clinical scenarios, such as early neuropathy, soft-tissue swelling, skin ulcer, and suspected osteomyelitis. In most of these situations, magnetic resonance imaging (MRI) with or without contrast is the examination of choice. Most other imaging tests have complementary roles. For soft-tissue swelling or an ulcer, radiography and MRI with or without contrast are suggested. Bone scintigraphy with white blood cell scanning is used when MRI is contraindicated. In patients with diabetes without ulcers, radiography and MRI with or without contrast are suggested; bone scanning may be used when MRI is contraindicated.
