Figure 6:

Axial MRI in a 57-year-old female participant with a high likelihood of advanced fibrosis according to the fibrosis based on four factors (FIB-4) index. (A) Left to right: Elastogram, magnitude, and wave images obtained at three-dimensional MR elastography (MRE) show the region of interest (dotted outline) in a region of parallel wave propagation, avoiding the outer margin of the liver. (B) Left to right: Elastogram, magnitude, and wave images obtained at two-dimensional MRE show placement of the region of interest (dotted outline) in the region of parallel wave propagation, avoiding the outer edge of the liver. (C) MRI proton density fat fraction map shows placement of regions of interest (green circles) within different segments of the liver. Color bars alongside elastograms indicate a range of kilopascals from low (purple) to high (red).
