Core Tip

Core Tip: The measurement of fat fraction was stable when using Iterative decomposition of water and fat with echo asymmetry and least squares estimation quantification sequence (IDEAL-IQ) before and after injection of hepatocyte-specific contrast agent. Such strong reproducibility makes IDEAL-IQ available in the interval for saving time during examination and optimizes the scanning protocol.
