Overview
A bone scan and a white blood cell scan are two imaging modalities that can be used to assist physicians to better diagnose the diabetic foot ulcerations. Both could be used when there is a high clinical suspicion for osteomyelitis, while plain X-rays are negative. A leukocyte or white blood cell scan has a higher specificity for ostemyelitis diagnosis and is accurate even in neuropathic patients, in contrast to the bone scan.
Other Imaging Findings
Bone Scan
- A bone scan could be used when there is a high clinical suspicion for osteomyelitis, while plain X-rays are negative.[1]
- A bone scan is not accurate in neuropathic patients since it might become falsely positive in the presence of hyperemia or charcot joint.
White Blood Cell Scan
- A leukocyte or a white blood cell scan could be used when there is a high clinical suspicion for osteomyelitis, while plain X-rays are negative.[1][2]
- In contrast to bone scan, it is reliable even in neuropathic patients.
- A leukocyte or a white blood cell scan has a higher specificity for ostemyelitis diagnosis compared to the bone scan.
