OBJECTIVE. The purpose of this study was to describe a novel technique for the 3D visualization of a liver segment on sonography, using a second-generation contrast agent in a dog, that would be applicable for anatomic hepatic resection.

CONCLUSION. After a mixture of YM454 and indigo carmine was injected into a portal vein branch, well-delineated 3D segmental staining was seen for approximately 10 minutes in harmonic mode sonography. The addition of indigo carmine significantly prolonged the contrast effect of YM454.

Keywords: animal studies • contrast media • harmonic sonography • liver • sonography
