Pathologic caudate–right-lobe ratio (CRL) in a patient with hepatitis B induced liver cirrhosis (MRI, T2 weighted haste): hypertrophy of the left and atrophy of the right liver. A dashed line parallel to the midsagittal plane was drawn through the right lateral wall of the first bifurcation of the right portal vein. The two distances of the caudate lobe (C) and right lobe (R) were divided and defined as the caudate–right-lobe ratio (CRL). The sum of the three liver vein diameters (LD) equals 12.1 mm. LD divided by CRL equals the CT fibrosis score, which is below 20 and therefore compatible with liver cirrhosis.
