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.
目的
本研究旨在描述一种利用第二代造影剂在犬类中对肝脏某一肝段进行超声三维可视化的新技术，该技术适用于肝脏解剖性切除术。
结论
将YM454与靛胭脂混合液注入门静脉分支后，在谐波模式超声检查中，可清晰看到三维肝段染色，持续约10分钟。靛胭脂的加入显著延长了YM454的造影效果。
