简要总结
Diabetic foot osteomyelitis (DFO) is a bone infection of the foot that can occur in people with diabetes and may lead to serious complications, including amputation. Diagnosing DFO can be difficult. This prospective multicenter observational study will evaluate how accurately 18F-FDG PET/CT can diagnose DFO in patients who are already referred for this imaging test as part of their clinical care. The study will use current-generation digital PET/CT systems and standardized interpretation criteria. PET/CT findings will be compared with bone biopsy results when available, or with clinical and imaging findings obtained during at least 6 months of follow-up.

研究组 & 干预措施
Patients with suspected diabetic foot osteomyelitis
Adults with diabetes and suspected diabetic foot infection with concern for osteomyelitis who are referred by their treating physician for 18F-FDG PET/CT. Participants will undergo standard clinical care and will be followed through medical record review for at least 6 months to establish the final diagnosis and clinical outcomes.
干预措施: 18F-FDG PET/CT (Diagnostic Test)
结局指标
主要结局
Diagnostic accuracy of 18F-FDG PET/CT for diabetic foot osteomyelitis
时间窗: At least 6 months after PET/CT
Diagnostic performance of 18F-FDG PET/CT for diabetic foot osteomyelitis will be assessed by calculating sensitivity, specificity, positive predictive value, and negative predictive value. PET/CT findings will be compared with a reference standard consisting of histopathology from bone biopsy when available, unequivocal cortical erosion/destruction on CT, or clinical and radiographic/CT confirmation during follow-up.
