Quantifying Metal Artefact Reduction using Virtual Monochromatic Dual-Layer Detector Spectral CT Imaging in Unilateral and Bilateral Total Hip Prostheses

Highlights • Dual-layer detector CT reduces metal artefacts at high monochromatic energies (keV). • 130 keV images were optimal based on quantitative analysis on CNRs. • Optimal keVs varied from 74–150 keV for different hip prostheses configurations. • The Titanium alloy resulted in less severe arte...

Description
Summary:Highlights • Dual-layer detector CT reduces metal artefacts at high monochromatic energies (keV). • 130 keV images were optimal based on quantitative analysis on CNRs. • Optimal keVs varied from 74–150 keV for different hip prostheses configurations. • The Titanium alloy resulted in less severe artefacts compared to the Cobalt alloy. • Severe metal artefacts, caused by extensive photon-starvation, were not reduced
