Contrast Media | Radiology Key

The negative contrast agents can also be used in conjunction with a positive contrast agent. One common procedure that uses this coination of contrast agents is the double contrast barium enema. Air and oxygen may be dangerous during certain procedures because they can cause gas eoli, but carbon dioxide and nitrogen do not pose the risk of gas eoli and can be used with relative safety.

Carbon nanoparticles as a multimodal thermoacoustic …

We demonstrated the potential of carbon nanoparticles (CNPs) as exogenous contrast agents for both thermoacoustic (TA) tomography (TAT) and photoacoustic (PA) tomography (PAT). In comparison to deionized water, the CNPs provided a four times stronger signal in TAT at 3 GHz. In comparison to blood, The CNPs provided a much stronger signal in PAT over a broad wavelength range of 450-850 nm
