- Background: The aim of this prospective study was to assess the diagnostic value of nuclear imaging with F-18-FDG PET/CT (FDG PET/CT), combined In-111-WBC/(99)mTc-Nanocoll, and Tc-99m-HDP SPECT/CT (dual-isotope WBC/bone marrow scan) for patients with chronic problems related to knee or hip prostheses (TKA or THA) scheduled by a structured multidisciplinary algorithm.Materials and Methods: Fifty-five patients underwent imaging with Tc-99m-HDP SPECT/CT (bone scan), dual-isotope WBC/bone marrow scan, and FDG PET/CT. The final diagnosis of prosthetic joint infection (PJI) and/or loosening was based on the intraoperative findings and microbiological culture results and the clinical follow-up.Results: The diagnostic performance of dual-isotope WBC/bone marrow SPECT/CT for PJI showed a sensitivity of 100% (CI 0.74-1.00), a specificity of 97% (CI 0.82-1.00), and an accuracy of 98% (CI 0.88-1.00); for PET/CT, the sensitivity, specificity, and accuracy were 100% (CI 0.74-1.00), 71% (CI 0.56-0.90), and 79% (CI 0.68-0.93), respectively.Conclusions: In a standardized prospectively scheduled patient group, the results showed highly specific performance of combined dual-isotope WBC/bone marrow SPECT/CT in confirming chronic PJI. FDG PET/CT has an appropriate accuracy, but the utility of its use in the clinical diagnostic algorithm of suspected PJI needs further evidence.
