It supplements information obtained by intensive preoperative investigations enables make more precise limited resections than were previously possible. provides greater range options management hepatocellular carcinoma. The confronted with malignant tumour should base his decision resection characteristics: secondary, extra- intrahepatic spread, position, histological differentiation presence absence cirrhosis.
