Quantitative measurements of second harmonic and first harmonic Doppler were carried out using two ultrasound contrast agents, Albunexc and FS069. The RMS amplitudes of the Doppler shift spectra were measured as a function of the concentration of the agents, frequency and transmitted acoustic pressu

## Abstract ## Purpose To investigate three different contrast agents at different injection volumes for repetitive quantitative multislice myocardial perfusion imaging using the prebolus technique. ## Materials and Methods Two consecutive prebolus perfusion measurements were performed on a 1.5T
