Seventy specimens of solid hepatic tumors were obtained for histologic examination with a 18 G (1.2 mm) diameter needle under real-time ultrasound control. Overall sensitivity was 95.6 p. 100 while specificity was 100 p. 100. Distinction between primitive and secondary malignant tumor was possible in 91 p. 100 of cases. Transient hemorrhage at the puncture site occurred in one patient. These results attest to the superiority of guided puncture with a needle of sufficient caliber, thus allowing for correct histologic study. Side effects did not occur more frequently than with fine caliber needles.
