BACKGROUND AND PURPOSE: Metal-related artifacts from spine instrumentation can
obscure relevant anatomy and pathology. We evaluated the ability of CT images …

Metal hardware serves as a common artifact source in spine CT imaging in the form of beam-
hardening, photon starvation, and streaking. Postprocessing metal artifact reduction …

Aim To investigate the value of dedicated computed tomography (CT) iterative metal artefact
reduction (iMAR) algorithms in patients after spinal instrumentation. Materials and methods …

OBJECTIVE. The objective of this study was to compare the capability of two algorithms for
metal artifact reduction and virtual monoenergetic imaging (VME), a metal artifact reduction …

OBJECTIVE. The purpose of this study was to evaluate the usefulness of a metal artifact
reduction (MAR) algorithm for orthopedic prostheses in phantom and clinical CT …

Three commercial metal artifact reduction methods were evaluated for use in computed
tomography (CT) imaging in the presence of clinically realistic metal implants: Philips O …

OBJECTIVE. The purpose of this study was to evaluate the performance of three metal
artifact reduction methods in dual-energy CT (DECT) examinations of instrumented spines …

Background Artifacts caused by metal implants are challenging when undertaking computed
tomography (CT). Dedicated algorithms have shown promising results although with …

The projectional nature of radiogram limits its amount of information about the instrumented
spine. MRI and CT imaging can be more helpful, using cross-sectional view. However, the …

Purpose To prospectively compare the effectiveness of iterative decomposition of water and
fat with echo asymmetry and least-squares estimation (IDEAL) T2-weighted and contrast …
