(i) Radionuclide imaging of joint prostheses: established & emerging applications

Bone and radiolabelled white blood cell scintigraphy are widely used in the evaluation of symptomatic joint prostheses. Emerging techniques including dual tracer scintigraphy, positron emission tomography - computed tomography (PET-CT) and immunoscintigraphy show promise as more specific tools for use in the assessment of prosthetic joint complications. This article will review the current and future role of radionuclide imaging in establishing the presence, and determining the cause of prosthetic joint complications.
