Coded Harmonic Imageによる造影US下リアルタイム穿刺

Tissue harmonic imagingでも、MI値を約0.2程度に設定することで、ソナゾイド®を使用した造影超音波が

LOGIQ E9, ultrasound sonogram system of GE Corporation, use phase inversion imaging in contrast
enhanced mode. However, we cannot see the needle clearly in this image and further development of
imaging is warranted. We used tissue harmonic imaging with low mechanical index in contrast enhanced sonography, and it could show clearly both the target lesion enhanced by perflubutane and the needle.
We reported two cases in which this imaging was useful for radiofrequency ablation of hepatocellular carcinoma.
