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
