Core Tip
Core tip: The role of three dimensional gradient echo sequence with volumetric interpolated breath-hold examination (VIBE) by using chemically selective fat-saturation for abdominal magnetic resonance (MR) imaging is well established and it is now part of the standard clinical work-up, especially for dynamic contrast-enhanced liver MR imaging. The Dixon technique has been improved extensively in the aspects of phase errors, noise and artifacts. There are no reports yet on the potential value of two-point Dixon fat-water separation technique for image quality and focal liver lesions in hepatobiliary phase of gadoxetic acid-enhanced MR imaging. Therefore, we compare the image quality and liver-to-lesion contrast in hapatobiliary phase between VIBE using two-point Dixon fat-water separation and chemically selective fat saturation.
