Molecular imaging is a rapidly growing field with the potential to revolutionize cardiovascular medicine by shifting diagnostic focus from functional abnormalities which occur late in a disease process to the biochemical events which precipitate the earliest stages of disease.

When used in central venous injections for digital subtraction angiography, sodium meglumine ioxaglate (Hexabrix) has been found to be associated with a high incidence of nausea and vomiting (24.5%), when compared with iohexol (Omnipaque) (0%) in 101 patients.

Current Pharmaceutical Biotechnology, 2004
The relative non-specificity of the first generation MR contrast agents has meant that a new approach to their design is required. This review focuses on a new class of more specific or functional agents. These are the so-called "activated", "smart" or "responsive" contrast agents.

Relaxometry and Contrast Agents
2018The perturbation on the relaxation of solvent water protons induced by the presence of paramagnetic metal-containing systems has been exploited for the design of contrast agents in magnetic resonance imaging applications. Complexes of Gd3+ ions were identified early as the candidates of choice and several, highly stable, Gd-containing contrast agents ...

MR Angiography Contrast Agents
2010Gadolinium-based agents are the most widely employed agents for CE-MR angiography. They act as positive paramagnetic substances, thus they increase the vascular signal by strongly reducing the T1 relaxation time of blood. Several Gd-based agents have been approved for clinical application to date.

Contrast Agents: Magnetic Resonance
2008Even though the intrinsic magnetic resonance imaging (MRI) contrast is much more flexible than in other clinical imaging techniques, the diagnosis of several pathologies requires the involvement of contrast agents (CAs) that can enhance the difference between normal and diseased tissues by modifying their intrinsic parameters.

Contrast agents are divided into two categories. The first one is paramagnetic compounds, including lanthanides like gadolinium, which mainly reduce the longitudinal (T1) relaxation property and result in a brighter signal. The second class consists of super-paramagnetic magnetic nanoparticles (SPMNPs) such as iron oxides, which have a strong effect on
