Ultrasound Contrast Agent Microbubble Dynamics [PDF]
, 2010 Ultrasound contrast agents are traditionally used in ultrasound-assisted organ perfusion imaging. Recently the use of coated microbubbles has been proposed for molecular imaging applications where the bubbles are covered with a layer of targeting ligands

Nano-Sized Ultrasound Contrast Agent: Salting-Out Method
Molecular Imaging, 2010 Tumor imaging by ultrasound is greatly enhanced by the use of ultrasound contrast agents (UCAs), stabilized, gas-filled bodies. They are generally less than 7 μm to pass freely through the capillary bed.

Stable Thermally-Modulated Nanodroplet Ultrasound Contrast Agents
Nanomaterials, 2021 Liquid perfluorocarbon-based nanodroplets are stable enough to be used in extravascular imaging, but provide limited contrast enhancement due to their small size, incompressible core, and small acoustic impedance mismatch with biological fluids.
