The results of ultrasound and computer tomography in 150 patients with possible focal liver disease were compared. Ultrasound was more sensitive than CT in detecting lesions but similar information on the nature of the lesions was obtained with both methods. CT provided more complete information than US on the extent of the lesion. Thus, CT and US are supplementary in the evaluation of focal liver disease. Because of the higher sensitivity US should be the first examination, followed, if clinically indicated, by CT confirmation and possible further information regarding the extent of the lesion.
