intracardiac shunts, left ventricular opacification ,refined definition of LV
structural abnormalities, enhancement of
Doppler signals and myocardial perfusion
, Bubbles produced are--- to traverse the pulmonary vasculature and contrast will
remain in the right heart only- unless a right to left shunt exists

Contrast agents also enhance Doppler signals

i. Contrast may be used to enhance TR signals to assess right heart
pressures
ii. Contrast may be used to enhance weak aortic stenosis jets and also weak
pulmonary vein flow profiles
1. It should be noted that the use of contrast during color flow imaging will
result in color flow signal degradation
Ideas for the use of manufactured contrast agents originated from the observance of
