Imaging of liver metastases with contrast-specific low-MI real-time ultrasound and SonoVue

In summary, the study shows marked improvement in characterisation of focal liver lesions by the use of SonoVue. Overall, the number of correctly diagnosed lesions improved from 41 of 63 (65%) on baseline US to 58 of 63 (92%) after contrast (p<0.001). Comparison with the literature suggests that CEUS is superior to CT and equivalent to MRI in this application [14-16]. The most important aspect of these results with regards to imaging cancer patients is the increase in specificity, i.e. the improved ability to recognise benign lesions and to rule out metastases.
