Magnetic resonance elastography (MRE) is a powerful tool that can grade liver fibrosis non-invasively. In comparison with 2D MRE, 3D MRE can provide additional biomechanical tissue parameters for evaluating liver fibrosis. However, there is a great need to develop a quality assurance protocol for 3D MRE measurements. In this study, we have investigated quality assurance parameters for a 3D MRE research system and identified the cut-off values of the quality parameters to assign the 3D MRE data into three quality categories. A confidence map was constructed based on the evaluation of these quality parameters.
