Delaney LJ, Tantawi M, Wessner CE, et al. - This study was undertaken to investigate if quantitative contrast-enhanced ultrasound (CEUS) can predict the long-term response of hepatocellular carcinoma (HCC) to yttrium-90 (Y-90) treatment. Researchers enrolled a total of 15 individuals who had undergone CEUS at three time points: immediately following treatment and 1 and 2 wk post-treatment. Using the Modified Response Evaluation Criteria in Solid Tumors, response 3–6 mo after treatment was categorized on contrast-enhanced magnetic resonance imaging by two experienced radiologists. The results imply CEUS may provide an earlier indication of Y-90 treatment response than cross-sectional imaging.
