Definition:A calculated measurement in which the number of tumorous lesions in the liver is divided by the total volume of that liver and presented as a ratio, fraction, quotient or percentage. A tumorous lesion is a localized pathological change which is or has the potential to become a tumor, that is, a neoplasm or new growth of tissue in which cell multiplication is more or less uncontrolled and progressive. Tumorous lesions include tumors, preneoplastic lesions, and hyperplastic lesions composed of histologically normal cells.
