Hip prosthetic material and a steel rod were scanned in a water bath of fluorine 18 fluorodeoxyglucose (FDG) with positron emission tomographic (PET) and PET/computed tomographic (CT) scanners to evaluate the generation of artifacts adjacent to the metal. The influences of attenuation correction (AC), positioning of the object, and image reconstruction were examined. Use of CT- and germanium 68-based AC resulted in generation of artifacts that mimicked increased FDG uptake. These artifacts were… CONTINUE READING
