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

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.

Iodinated contrast agents in neuroradiology
Neuroimaging Clinics of North America, 1994Intravascular iodinated contrast materials in neuroradiology commonly are used during CT scanning and cerebral arteriography. This article discusses their use and the selection of appropriate contrast media. Adverse contrast media reactions, with emphasis on neurotoxicity, and the use of low osmolar agents are discussed.

Imaging is reliant upon the contrast between different body elements, which may be present naturally or may require the introduction of extrinsic contrast agents. Since the 1920s, the use of contrast agents has been refined to enhance the diagnostic potential of multiple imaging modalities.

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.
