| Research Abstract |
ARFI (Acoustic Radiation Force Impulse) that is used to evaluate tissue elasticity was examined about the thermal elevation and tissue damage on the animal tissues with or without ultrasound contrast agent (UCA). 1 to 5 degree C elevation was found on the liver with no effect of UCA. On the bone surface, temperature rose 2 to 6 degree C. The findings of cell death were not found on the liver tissue. Only under administration of UCA, premature ventricular complex was found when ARFI was applied on the heart.
