[Technique of application of contrast media in computed tomography of the heart (author's transl)].

Cardiac imaging by means of CT requires administration of intravenous contrast medium which can be applied by infusion or by rapid bolus injection. Contrast infusion is easier in performance and yields opacification of all cardiac cavities. Using bolus technique selective enhancement of cardiac chambers can be obtained which provides increased image quality and better resolution of cardiac structures. Both techniques are described and the results of 221 examinations are analysed with special respect to image quality, technical amount and contrast media side effects.
