Impact of computed tomography metal artifact reduction protocol on periprosthetic tissue characterization after total hip arthroplasty: A cadaveric study

Abstract: Metal artifact reduction (MAR) has improved computed tomography (CT) imaging of total hip arthroplasty (THA) but the assessment of osteolysis and implant to bone contact relies on the accurate depiction of bone defects, cancellous bone, and cement. This study evaluates the impact of available single and dual-energy protocols on periprosthetic tissue characterization in a cadaveric phantom. Bilateral THA was performed on a fresh frozen cadaveric pelvis with simulated osteolytic cavities. CT acquisitions with pr… Show more

“…Despite numerous studies in the past decades, the issue of metal artefacts in CT scans remains a significant problem. [39][40][41] Nevertheless, to achieve clinical sarcopenia diagnosis using CT scans, it is necessary to establish psoas muscle volume data for the general population and compare them with existing sarcopenia measurement methods. The AI software described in this study is expected to make a substantial contribution towards achieving these objectives.…”
