microbubbles

Tiny bubbles of gas, used as a contrast medium in ultrasound scanning, which are introduced into the vascular system or the Fallopian tubes to enhance the images obtained.

With CEUS, the boundaries of infarcted lesion could be clearly outlined as microbubbles could not be taken up in non-perfused region.[16] CEUS is considered as accurate as CT for the detection of vascular defects of the infarcted organs, and this technique is easily applicable to critically ill patients at the bedside.[17]

Traditional ultrasound contrast agents, that are a few micrometers in diameter and in the terms of gas-filled microbubbles, are often coated with lipids or biopolymers, and they are available for enhancing the reflection signal-to-noise ratio for blood [141].
Detecting right-to-left shunt by contrast was defined as echocardiographic evidence of infused microbubbles in the left atrium within three cardiac cycles after their appearance in the right atrium, at rest or during Valsalva release.
As the energy pulse of the laser is raised, the temperature of the melanosomes in the RPE cells within the laser-irradiated area increases, and microbubbles are generated.
