  2. Test Sensitivity: 78 to 99% (82-100% in Diabetic Foot Osteomyelitis)
  3. Test Specificity: 60 to 90% (75-96% in Diabetic Foot Osteomyelitis)
    1. False Positives with Osteoarthropathy and in regions of surgical hardware
  • Protocol
  1. Perform with IV Contrast (preferred)
  • Advantages
  1. Defines infection boundaries including anatomic landmarks
  2. Best distinguishes soft tissue infection from Bone Infection
