"The microbubbles utilised as contrast agent for CEUS are inherently sensitive to insonation, thus the mechanical index (MI) of ultrasound pulses has to be kept at the lowest possible level which provides reliable contrast, and is generally much lower than during routine B-mode US. When flash mode is triggered by the user, the probe emits a short US pulse with a very high MI (typically at least a magnitude greater than that of the CEUS preset itself). This pulse instantly and permanently destroys almost all microbubbles within the imaging plane 1. The "flash" is visible in the CEUS-view as a sudden, bright flare - hence the name."
