The lesion-to-liver contrast ratio is calculated using the following equation: lesion-to-liver contrast ratio equals “a” divided by “b”. a Peak intensity of the lesion (in arbitrary units), b intensity of the liver parenchyma at the time to peak intensity of the lesion, c time to peak intensity of the lesion (in seconds)
