Basu et al. [23] have shown that, in the evaluation of suspected knee and hip prosthetic infection, FDG PET provides superior accuracy compared with combined bone marrow and leukocyte scintigraphy (80–98% vs 25–96%). The sensitivity of combined bone marrow and leukocyte scintigraphy is 30–35%. However, Vanquickenborne et al. [24] found similar sensitivity, but slightly lower specificity in the evaluation of patients with a suspected hip prosthetic infection using FDG PET compared with combined bone and leukocyte scintigraphy. Van Acker et al. [25] also showed that PET has no additional benefit over combined bone and leukocyte scintigraphy in the evaluation of total knee arthroplasties.Read More: https://www.ajronline.org/doi/full/10.2214/AJR.17.18523
