"image level: axial slice immediately below the bifurcation of the main portal vein"
"line 1: parasagittal line drawn through the right lateral border of the main portal vein"
"line 2: parasagittal line drawn through the left lateral border of the caudate lobe"
"line 3: line orthogonal to lines 1 and 2 midway between the main portal vein and the inferior vena cava extended to the right liver edge"
"caudate measurement (C): along line 3, between lines 1 and 2"
"right lobe measurement (RL): along line 3, from right liver edge to line 1"
"caudate-right lobe ratio: C/RL"
"The caudate-right lobe ratio (C/RL) is used in the assessment of the liver, usually in the setting of cirrhosis, where there is atrophy of the right lobe with hypertrophy of the caudate lobe."
