Metal Artifact Reduction by Dual-Energy Computed Tomography Using Energetic Extrapolation: A Systematically Optimized Protocol
Investigative Radiology, 06/20/2012
Meinel FG et al. – Sn140/100 kVp with a tube current ratio of 3:1, a collimation of 32 × 0.6 mm, and extrapolated energies of 105 to 120 keV are optimal parameters for a dedicated dual–source computed tomography (DSCT) protocol that effectively reduces metal artifacts by energetic extrapolation. The protocol effectively reduces metal artifacts in all types of metal implants. The optimized reconstructions yielded relevant additional findings.
