A mosaic pattern is produced by mixing of different colored pixels in close proximity. A mosaic pattern typically indicates turbulent flow.

The motion discrimination detector is used for signal processing in color Doppler systems to distinguish between Doppler shifts from moving blood and moving tissue.

MP1950 is an experimental thin lipid-shelled ultrasound contrast agent with a decafluorobutane gas core. MP1950 has a monolayer lipid microbubble shell with a thickness in the order of a few nanometers.

MRX 115 is a liposome based microbubble formulation and has been demonstrated as effective for cardiac blood pool imaging, Doppler enhancement and potentially myocardial perfusion imaging.
MRX 115 is based upon the demand for a stable, robust blood pool ultrasound contrast agents, also called DMP 115 or Aerosomes™ (ImaRx LLC) and now Definity®.

MRX 408 is an investigational thrombus-specific ultrasound contrast agent for clot detection and sonothrombolysis enhancement. Targeted contrast imaging with this GPIIb receptor-targeted ultrasound contrast agent demonstrated better visualization of thrombus within AV fistulae.
MRX 408 is available (ImaRx LLC) with a mean radius of 1.0 mm and a standard deviation of 0.8 mm.
