ABSTRACT:
The invention relates to a method for differentially representing myocardial tissue in different states of damage, comprising the following steps: administering a myocardium-suitable contrast agent to a patient under examination; entering at least one patient-specific parameter affecting the speed of uptake by and elimination from the myocardium of said contrast agent; calculating a point in time after administration of the contrast agent at which a difference between a contrast agent content in necrotic myocardial tissue and a contrast agent content in non-necrotic myocardial tissue attains a maximum value, on the basis of the at least one patient-specific parameter, and carrying out, at the point in time calculated, a late-phase CT scan for accentuation of necrotic myocardial tissue compared to non-necrotic myocardial tissue. The invention likewise relates to apparatus, in particular for carrying out the method.
