Potential clinical role of 18F FDG-PET/CT in detecting hip prosthesis infection: a study in patients undergoing two-stage revision arthroplasty with an interim spacer.
We evaluated the potential role of [18F]fluorodeoxyglucose-positron emission tomography/computed tomography ([18F]FDG-PET/CT) to identify latent infections at the site of an interim hip spacer after resection arthroplasty for hip prosthesis infection. ⋯ FDG-PET/CT is highly sensitive to detect latent infections in prosthetic hips and in interim hip spacers. The high negative predictive value of PET/CT scans is useful to rule out infections in patients with persistently elevated CRP levels. PET/CT might serve as an auxiliary tool to exclude latent infections in patients posing a clinical diagnostic dilemma.
