Magnetic Resonance Imaging. Extracellular MRI and X-ray contrast agents are characterized by their phar- cokinetic behaviour. After intravascular injection their plasma-level time curve is characeterized by two phases. They are excreted via the kidneys in unchanged form by glomerular filtration. Extracellular water-soluble contrast agents to be applied for X-ray imaging were introduced into clinical practice in 1923.

Magnetic Resonance Imaging (MRI) Contrast Agents (CAs) are exogenous species that are administered to human beings/animals to increase contrast in diagnostic images obtained by the MRI technique. Contrast enhancement is due to the paramagnetic properties of the CA species  .

MR contrast agents can be applied in a variety of ways to improve MRI . A brief discussion of MR contrasts agents with emphasis on those in current clinical use is as follows. Microscopy in Magnetic Resonance Imaging.

MR contrast agents can be applied in a variety of ways to improve MRI sensitivity for detecting and assessing ischemically injured myocardium. From: Comprehensive Toxicology, 2010. 1 Intravenous Agents. These are administrated through veins by means of injection. Narasimhan, Russell E. Jacobs, in Annual Reports on NMR Spectroscopy, 2005. Cellular imaging with MRM using T2 and.

Phase contrast magnetic resonance imaging (PC-MRI) is a specific type of magnetic resonance imaging used primarily to determine flow velocities. PC-MRI can be considered a method of Magnetic Resonance Velocimetry. It also provides a method of magnetic resonance angiography. Since modern PC-MRI is typically time-resolved, it provides a means of 4D imaging (three spatial dimensions plus time).

Magnetic resonance imaging is an established imaging method for the evaluation of the abdomen. Accurate assessment of the liver, spleen, pancreas, bile ducts, vascular structures, and retroperitoneal organs (eg, the kidneys, the collecting system, and the adrenals) are possible on MR imaging. The intravenous administration of MR contrast agents can frequently improve the examination and provide more specific diagnoses. The advent of more specific, hepatobiliary contrast agents has further improved the differential diagnostic process, particularly for MR imaging of the liver.

Extracellular MRI and X-ray contrast agents are characterized by their phar- cokinetic behaviour.After intravascular injection their plasma-level time curve is characeterized by two phases. The agents are rapidly distributed between plasma and interstitial spaces followed by renal elimination with a terminal half-live of approximatly 1–2 hours. They are excreted via the kidneys in unchanged form by glomerular filtration. Extracellular water-soluble contrast agents to be applied for X-ray imaging were introduced into clinical practice in 1923. Since that time they have proved to be most valuable tools in diagnostics.They contain iodine as the element of choice with a sufficiently high atomic weight difference to organic tissue. As positive contrast agents their attenuation of radiation is higher compared with the attenuation of the surrounding tissue. By this contrast enhancement X-ray diagnostics could be improved dramatically. In 2,4,6-triiodobenzoic acid derivatives iodine is firmly bound. Nowadays diamides of the 2,4,6-triiodo-5-acylamino-isophthalic acid like iopromide (Ultravist, Fig. 1) are used as non-ionic (neutral) X-ray contrast agents in most cases [1].
