Recent Advances in Molecular Magnetic Resonance Imaging of Liver Fibrosis

Figure 4

MR elastography images of the livers of a normal volunteer and a patient with cirrhosis. Anatomic images of a normal volunteer and of a patient with grade 4 fibrosis are shown in the far left column (a). The middle column of images shows wave image data in the liver and spleen superimposed on the corresponding anatomic images (b). The resulting elastograms are shown in the far right column (c). The wave images show that the shear wavelength was higher in the fibrotic liver than in the normal liver. The elastograms show that the mean shear stiffness of the fibrotic liver was much higher than that of the normal liver ( kPa versus  kPa, resp.). (Reprinted with permission from [29].)
