For infarct or ischemia diagnostics, delayed gadolinium late enhancement imaging is currently the method of choice. However, there is abundant evidence that the infarct characterization is not sufficient and that there is a need for complementary information (Grey zone imaging, T2 weighted imaging, T1 mapping and perhaps even diffusion imaging). For these reasons, we want to improve infarct diagnostics by developing, implementing and testing new contrast generation schemes. For accurate motion analysis, advanced myocardial tagging methods (such as in the image below) are being used.

 

The future of medical imaging is quantitative.
Most routine imaging techniques are quantitative i.e. the intensity of the images uses an arbitrary grayscale; such images cannot be directly compared to one another for anything besides anatomical differences. The alternative is to use an imaging technique that maps a physiological value to each pixel. Such physiolgical values (a relaxation time, concentration, or diffusion measure, for example) can be compared between patients, or patients can be used as their own control
