ag Demonstrates MRE sequence images of 28-year-old healthy normal LLD candidate with absolutely normal hepatic parenchyma and without neither steatosis nor fibrosis. The obtained MRE sequence images include the conventional anatomical reference image of MRE single slice (a) and the corresponding color-coded shear wave images (b, c), which were obtained by using vibration of 60 Hz, as well as the MRE inversion algorithm processed images including the color-coded elastogram with 0–8 kPa and 0–20 kPa (d, f, respectively), in addition to their associated confidence map images (e, g, respectively), in which the unsuitable portions for stiffness measurements were omitted (the shaded areas). The conventional anatomical reference image (a) reveals apparently normal hepatic tissue. The analysis of the corresponding color-coded shear wave images show narrow, regular, and shorter lengths of the obtained shear waves throughout the liver parenchyma, particularly in the right hepatic lobe (the arrows in b, c images). Also, the color-coded elastogram with 0–8 kPa and 0–20 kPa (d, f, respectively), as well as their associated color-coded confidence map images (e, g, respectively), demonstrate low hepatic stiffness, in which the valid portion for stiffness measurements were stained with blue (e) and purple (g) colors. According to the images’ corresponding color bars, these colors demonstrate the lowest stiffness. The mean estimated stiffness value of the liver, in the manually drawn ROIs, on the confidence maps (red and yellow rings on e and g images, respectively), was 1.90 kPa (average stiffness). The liver biopsy confirmed these findings
