Contrast agent nephrotoxicity: comparison of ionic and nonionic contrast agents
American Journal of Roentgenology, 1987The effects on glomerular and proximal tubular function of an ionic contrast agent (sodium meglumine diatrizoate) and a nonionic agent (iopamidol) were compared in 34 patients with normal renal function. The patients received large doses (2.5 ml/kg body weight) of contrast material for IV digital subtraction angiography. Urine samples, collected before,

Pharmacologic development and clinical use of nonionic low osmolality contrast agents have lowered incidences of contrast reactions. Exclusive use of these agents may be limited owing to their high costs. Ionic high osmolality agents still provide reliable means of positive contrast enhancement, and minimal problems with reactions have been experienced

Magnetoliposomes as Contrast Agents
2003Publisher Summary Liposomes are entirely biocompatible and are recognized as promising microvehicles for therapeutics and diagnostics in vivo and host either polar drugs in their aqueous inner space or lipophilic drugs in the lipid bilayer, protecting the entrapped pharmaceuticals from potential inactivation by external factors and without ...

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.
