Quantitative indices for ranking the severity of hepatocellular carcinoma.
A method for quantifying the severity of tumour burden based on fractional affected areas, weighted by their mean attenuation values relative to normal tissue, is presented. The procedure was applied retrospectively to routine computerized tomography (CT) scans of patients with hepatocellular carcinoma, and produced severity indices that reliably followed the ranking of an expert panel.
