✦ Synopsis

The nonlinearity parameter B/As of two contrast agents (Albunex and Levovist) in a saline solution (Isoton II) were measured. The results show that B/As of both contrast agents were increasing functions of bubble number densities. In general, they are much higher than that of most soft tissues. For Albunex (concentration = 1 microL Albunex: 1 mL Isoton) a B/A of 2000; and for Levovist (concentration = 6.0 mg Levovist powder: 1 mL Isoton), a B/A of 600 was obtained.

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 Current clinical applications of dynamic contrast‐enhanced MRI (DCE‐MRI) are based on the extravasation of relatively small contrast agents (SCAs). SCAs are considered disadvantageous, as they require high image sampling rates. Medium‐sized contrast agents (MCAs) leak more slowly into t
