We evaluated two commercially available methods for non-uniformity correction, an image-based method (SCIC) and a calibration-based method (PURE), in Gd-EOB-DTPA-enhanced MR imaging using a 3T scanner. SCIC improved uniformity for the precontrast images; however, artificial hyperintensity in the liver surface was evident especially in the hepatobiliary-phase images. Quantitative evaluation of contrast effects were severely distorted by SCIC. PURE improved uniformity in the precontrast and hepatobiliary-phase images, and appeared to aid quantitative evaluation of the signal intensity after contrast administration. PURE is indicated to be a useful non-uniformity correction method in Gd-EOB-DTPA-enhanced MR imaging using a 3T scanner.
