Quantification methods.
Ultrasound contrast agents can be assimilated to intravascular flow tracers opening the field of myocardial blood flow (MBF) quantification. However, tracer theories are invalidated because of microbubble unstable structure and peripheral injection. In order to overcome these limitations, new models have been developed as destruction/refilling sequences allowing MBF assessment.
