Detection of Osteomyelitis Using High Resolution Ultrasound

Inclusion Criteria: 1. Patient may be of any race and between 18-85 years of age. 2. Patient has a current diagnosis of a chronic ulcer with suspected osteomyelitis. 3. Patient's ulcer may be due to any etiology including but not limited to diabetes, trauma, neuropathic, pressure, venous, arterial, and inflammatory. 4. Patient's ulcer may extend through the dermis and into subcutaneous tissue (granulation tissue may be present), and may include exposure of muscle, tendon, bone, or joint capsule. 5. Patient's ulcer is suspected of causing a bone infection. 6. Patient's ulcer may be of any size. 7. Patient's wound may present with non-viable tissue. 8. Patient circulation to the wound should be evaluated and treated using normal protocol. 9. Patient's diabetes is under control as determined by the Investigator. Patients must have an HbA1c value less than 13.0%. Those patients whose glucose level is not deemed to be in control should be referred to their primary physician for treatment of the hyperglycemia. 10. Patient and caregiver are willing to participate in the clinical study and comply with the follow-up regimen. 11. Patient or his/her legal representative has read and signed the Institutional Review Board (IRB) approved Informed Consent form before treatment. 12. If patient is capable of childbirth, she is using medically accepted means of birth control, and she tests negative on a serum pregnancy test. 13. Active localized acute wound infection or cellulitis: Subject may be considered for study enrollment after the signs and symptoms of acute infection have resolved. Exclusion Criteria: 1. Subject has a condition where an MRI is contraindicated * Metallic fragments, clips or devices in the brain, eye, spinal canal, etc.: (Plain radiography is sufficient for screening * Magnetically activated implanted devices: Cardiac pacemakers, insulin pumps, neuro¬stim¬u¬lators, cochlear implants, etc. may be de-programmed. * Non-graphite spinal cord tongs: Graphite tongs are compatible. * Thermodilution Swan-Ganz catheter: Local heating can result. If unenhanced MRI is likely to provide sufficient information, gadolinium should not be administered to these patients. If, after review of clinical indications, gadolinium enhancement is judged to be important for diagnosis, the lowest effective dose of contrast agent should be used. 2. In subjects where gadolinium enhancement MRI is planned then the following exclusion criteria apply: * Subject is allergic to contrast materials or cannot tolerate gadolinium * Subject is at risk of nephrogenic systemic fibrosis (NSF) or has severe renal failure (as determined by the investigator) 3. Patient must not be pregnant. 4. Patient has any condition(s) that seriously compromises the patient's ability to complete this study. 5. Patient with recent surgical debridement of the bone in and around the ulcer site.
