Conventional (a), 130-keV monoE (b), conventional with O-MAR (c), 130-keV monoE with O-MAR (d), and DL-MAR (e) images of a patient with unilateral total hip arthroplasty at the middle of the prosthesis’ head. Three regions of interest were drawn on the conventional CT image and subsequently copied to the other reconstructed images to measure CT values and noise as the standard deviation in HU. Window: width 1,600, level 400 HU. CT Computed tomography, O-MAR Orthopedic metal artifact reduction, DL-MAR Deep learning-based metal artifact reduction
