| Popis: | A major feature of magnetic resonance imaging (MRI) is the great variation possible in the choice of suitable scanning sequences to obtain optimal image contrast and the desired tissue differentiation. As with any other procedure, the sensitivity and specificity of MRI and, hence, its accuracy can be enhanced through the use of contrast media (CM). Despite the use of appropriate imaging techniques, more exact conclusions about the tissue integrity, function and perfusion of certain organ systems can, in most cases, only be drawn with the help of CM. Their use can also simplify the examination procedure itself or obviate other diagnostic methods. Wide-spread clinical use had demonstrated definite advantages of contrast-enhanced MRI over the plain examination. At present, contrast media are used world-wide in more than 25% of all MR examinations, depending on the indication and clinical experience. |
