[Digital subtraction angiography for the assessment of myocardial perfusion].
Coronary angiography does not only permit to evaluate the severity of coronary disease but also to assess coronary flow reserve in various myocardial perfusion areas by digital processing. Use of colour flow mapping allows the assessment of both, density as well as distribution velocity of contrast-medium (= parametric imaging). The advantage of this technique is given by the possibility to assess coronary flow reserve not only at rest but also under physiologic situations such as bicycle ergometry. Clinical investigations have shown that coronary flow reserve determined after papaverine administration does not correlate with physiologic conditions such as physical exercise.
