Commercial phantoms for system calibration and validation are common for imaging modalities like CT and MRI, including resolution and flow phantoms. However, there currently are no commercial sources for a suitable liver-mimicking test phantom for MRE. The purpose of this study was to identify and test readily available and inexpensive materials that might be useful as simple test phantoms for hepatic MRE.
