title: Computed tomography in the evaluation of hepatocellular carcinoma.
abstract: Computed tomography (CT) was used to evaluate 47 cases of hepatocellular carcinoma: it was definite in 37, equivocal in 5 and negative in 5 cases. No specific patterns of CT images were recognized. Pre- and postcontrast scans were necessary because several tumors could only be detected on one or the other scan. CT may reveal the exact extent of tumor and show additional tumors in case of multiple lesions. However, false negative results are possible in isodense or very small tumors.
