Figure Lengend Snippet: A patient with stage 3 fibrosis and NASH underwent a SWE (using GE) with a reading of 2.04 m/s, an ARFI (Siemens ultrasound) with a reading of 2.60 m/s, a 2D MRE at 60 Hz (GE 3 Tesla) with a reading 4.5 K pa, and a 3D MRE at 60 hz (GE 3 Tesla) with a reading of 3.2 Kpa. These readings are suggestive of advanced fibrosis across all four modalities.
