要約(Abstract) :Existence of metal in magnetic resonance imaging (MRI) is very troublesome. In recent years, Iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL) using 3-points Dixon technique become used as the useful method for uniform fat suppression at the magnetic field inhomogeneity. However, misregistration artifact appeared under some conditions. Purpose of this study is searching for conditions of misregistration artifact on IDEAL method. We have created the phantom which had contained oil, water and the titanium. The relation of misregistration artifact and seed-point of region growing technique was analyzed by shifting the position of metal, changing the position of FOV. Misregistration artifact on IDEAL method was sometimes occurred to existence the metal at center of phantom under the each conditions.
