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 material-enhanced T1-weighted magnetic resonance (MR) imaging with that of a conventional MR imaging protocol in minimizing metallic artifacts in phantoms and in patients with metallic hardware after spinal surgery. MATERIALS AND METHODS Institutional review board approval and informed consent were obtained for this… CONTINUE READING
