[Ultrasonography in primary hepatic tumors: potentialities, limits and comparison with arteriography (author's transl)].

The echotomographic patterns in 22 patients with hepatic neoplasms are reported and discussed. Ultrasonography has a high sensitivity in detecting the solid echopattern of the tumour and its origin from liver parenchyma; gray-scale B-scan and a meticulous technique are very helpful for this purpose. Echotomography plays an important part in the diagnostic evaluation of this pathology, to better select the patients for more invasive techniques, after the screening procedures, as scintigraphy.
