[Value of scintigraphy with 111In-acetylacetone-labelled auto-leukocytes in the diagnosis of infected total endoprostheses].
Scintigraphy with 111In-acetylacetone-leucocytes is valuable in detecting infectious processes in alloarthroplasties of the hip and knee. The sensitivity of 95% is high whereas the specificity of 74% is low due to the high incidence of falsely positive results. These are seen mainly in aggressive granulomas of the hip caused by alloarthroplasties using metal sockets and polyethylene heads. Since those alloarthroplasties are no longer used the incidence of falsely positive scans will decrease and the specificity of the method is likely to increase.
