A simple ultrasonic method for evaluating liver size

By measuring the liver area (maximum seciton) and plotting this against intra-abdoinal area at the same level, one can calculate tolerance levels for 80 per cent of the population (63 normal patients) with a 95 per cent confidence. This provides a simple semiquantitative index in relating liver size of a specific patient to the normal range. Its use in 14 patients with liver disease was demonstrated.
