How I Discovered Bronzin’s Bookcrobubbles as the contrast agent, whereas intravenous techniques use Levovist (300 mg/ml), the only contrast agent currently marketed in Japan. Intravenous contrast-enhanced US can be further classified into contrast-enhanced Doppler and contrastenhanced harmonic techniques. The former utilizes fund

In the case of contrast agents for intravenous administration, microbubbles must pass through the capillaries in the lungs, and therefore can be no larger than about 8 μm in diameter. Because of this limitation, the scattering intensity obtained with

Joseph A. Zehnder,Susanne Grossman-Clarket when microbubbles decompress, they freely become large. Accordingly, while transmitted waves are sine waves, reflected signals are, in comparison, greatly distorted. Waveform distortion means the generation of harmonic signals, which are several integral times larger than those of the transmitted
