VASCULAR AND INTRAVASCULAR RESPONSES TO VARIOUS CONTRAST MEDIA
- MORPHOLOGIC CHANGES IN VESSEL ENDOTHELIA CAUSED BY CONTRAST MEDIA. Zinner, G.; Gottlob, R. // Angiology;Aug1959 Part 1, Vol. 10 Issue 4, p207
Investigates the effect of contrast media on the alteration of blood vessel endothelia. Morphologic changes found in the vascular tissue after utilization of the medium; Mechanism for the local damage in the vessel intima; Means to prevent damage by the contrast medium during angiography.
- Iodinated contrast media alter immune responses in pro-inflammatory states. O'Donnell, David H.; Moloney, Michael A.; Bouchier-Hayes, David J.; Lee, Michael J. // Acta Radiologica;Jul2010, Vol. 51 Issue 6, p635
Background: Hypertonic saline causes a transient elevation of blood osmolality and has been shown to alter cellular inflammatory responses in pro-inflammatory states. Intravascular administration of iodine contrast media also causes a transient elevation of blood osmolarity. Purpose: To...
- Iomeprol: A Review of its Use as a Contrast Medium. Dooley, M.; Jarvis, B. // Drugs;May2000, Vol. 59 Issue 5, p1169
Iomeprol is a nonionic, monomeric iodinated contrast medium. Unlike the older ionic agents, iomeprol has low chemotoxicity, osmolality and viscosity and high water solubility. Compared with other nonionic contrast media, the osmolality and viscosity are lower and the water solubility is reported...
- CONCEPTS FOR APPLICATION OF CONTRAST MEDIA IN PERIPHERAL MRA. Boos, M.; Bongartz, G. // Acta Radiologica;Apr2000 Supplement 422, Vol. 41, p58
Describes and approach for contrast-enhanced magnetic resonance angiography (MRA) of the peripheral vascular system. Limitations of peripheral MRA; Peripheral MRA protocols; Image quality; Clinical accuracy.
- OPTIMIZATION OF PERIPHERAL MRA. Leiner, T.; Ho, K.Y.; Nelemans, P.J.; van Engelshoven, J.M.A. // Acta Radiologica;Apr2000 Supplement 422, Vol. 41, p58
Studies improvements in three-dimensional contrast-enhanced moving-bed peripheral magnetic resonance angiography. Selection of scan parameters; Peripheral imaging protocols; Image quality.
- Mechanochemical Synthesis of Yttrium and Lanthanum Tantalates. Molchanov, V. V.; Zuev, M. G.; Plyasova, L. M.; Bogdanov, S. V. // Inorganic Materials;Jan2004, Vol. 40 Issue 1, p73
The phase changes in the Y2O3â€“Ta2O5 and La2O3â€“Ta2O5 systems during mechanical activation and subsequent heat treatment are investigated. Y2O3 and Ta2O5 are shown to react during mechanical activation to form Y3TaO7 . Calcination of activated mixtures leads to the formation of YTaO4...
- Adverse Effects of Contrast Media: Incidence, Prevention and Management. Thomsen, H.S.; Bush, W.H.J. // Drug Safety;Oct1998, Vol. 19 Issue 4, p313
Although contrast media are relatively well tolerated, a non-life-threatening, moderate reaction requiring some treatment occurs in 1 to 2% of patients receiving ionic high-osmolar contrast media and in 0.2 to 0.4% of patients receiving non-ionic low-osmolar contrast media. Severe,...
- Functional CT imaging in oncology. Miles, K. A. // European Radiology;Dec2003 Supplement 5, Vol. 13, pM134
The two-compartment pharmacokinetics exhibited by iodinated contrast media makes these agents well suited to the study of tumour angiogenesis in which new vessels are not only produced in greater number but also are abnormally permeable to circulating molecules. The temporal changes in contrast...
- Vascular Reactions of Iodinated X-Ray Contrast Media: Mechanisms and Possible Therapeutic Interventions. Uder, Michael; Heinrich, Marc // Anti-Inflammatory & Anti-Allergy Agents in Medicinal Chemistry;May2006, Vol. 5 Issue 2, p129
Vascular reactions after administration of all classes of iodinated x-ray contrast media are well known side effects of these drugs. Both vasodilation and vasoconstriction have been observed. The manner and extent of the change in vessel tone depends on the type of contrast medium, species,...
