Figure 2. — Effect of iMAR on mean HU ± 95% CI of the most artifact-affected anatomical structures M. gluteus maximus, M. iliopsoas and bladder in the vicinity of hip endoprostheses. iMAR corrected CT HU marked with asterisks differ significantly from noMAR CT HU (*= p < .05; **=p <.01) (b) Effect of iMAR on mean voxelwise HU standard deviation ± 95% CI of the most artifact-affected anatomical structures M. gluteus maximus, M. iliopsoas and bladder in the vicinity of hip endoprostheses. iMAR corrected CT HU marked with asterisks differ significantly from noMAR CT HU (* = p< .05; **=p <.01). CI, confidence interval; HU, Hounsfield unit; iMAR, iterative metal artifact reduction.
