A group of 6 healthy and 9 NAFLD-patients underwent a multi-parametric MRI examination, including 4D-, 2D-flow, MRE and relaxometry. 2D-flow results were successfully extracted from 4D-flow data, showing good match with 2D-flow, indicating that 4D-flow provides the opportunity to both provide regular flow values as well as additional information e.g. flow visualizations. Correlation between 4D-flow and spleen volume indicate that 4D-flow could provide markers for early portal hypertension.
