Liver lesions: intermittent second-harmonic gray-scale US can increase conspicuity with microbubble contrast material-early experience

Radiology. 2000 Aug;216(2):592-6. doi: 10.1148/radiology.216.2.r00au31592.

Abstract

The authors investigated the effect of intermittent second-harmonic gray-scale (ISHGS) ultrasonography (US) with SH U 508A microbubbles on the conspicuity of focal liver lesions. Twenty-three patients were included in the study. Images were analyzed subjectively and quantitatively. Objective lesion conspicuity was increased. In 12 of the 15 patients with liver malignancy, gray-scale defects were seen in previously unsuspected areas. ISHGS US may improve the sensitivity of US for liver lesions.
