As reviewed by Roth et al [22], these artifacts are related to both the prosthesis (eg, type of metal and geometry) and the scanning parameters. Several techniques have been used to reduce these artifacts (termed MAR) [22,23]. Fluorine-18-2-fluoro-2-deoxy-D-glucose (FDG)-PET/CT Skull Base to Mid-Thigh and Fluoride PET/CT Skull Base To Mid-Thigh: PET studies (using either FDG or fluoride) may be tailored to focus imaging of the area of interest, Reprint requests to: publications@acr.org Imaging After Total Hip Arthroplasty such as the hip, rather than including the entire region of the skull base to mid-thigh. Many of the investigations included in this document were performed before the widespread availability of PET/CT, and consequently, they were performed as PET studies without CT. Bone Scan Hip Periprosthetic uptake can be present for a year or more after prosthetic insertion [25-27]. Therefore, bone scintigraphy of the hip for routine surveillance of asymptomatic hip arthroplasties is not supported. Bone Scan with SPECT or SPECT/CT Hip Data on the normal evolution of periprosthetic uptake on single-photon emission computed tomography (SPECT) or SPECT/CT of the hip following hip arthroplasty are lacking [28]. However, on planar bone scintigraphy, persistent periprosthetic uptake can be present for more than 1 year following implantation [25-27]. Consequently, bone scintigraphy with SPECT or SPECT/CT is not supported for routine surveillance of asymptomatic hip arthroplasties. CT Hip There are no recent studies advocating routine CT scanning of the hip for asymptomatic patients with conventional or MoM prostheses. Fluoride PET/CT Skull Base to Mid-Thigh It can take a year or more for periprosthetic uptake to normalize around a hip prosthesis [29,30]. Therefore, fluoride PET/CT skull base to mid-thigh is not supported for routine surveillance of asymptomatic hip arthroplasties.
