We focus on researching MR imaging and spectroscopy of the heart and skeletal muscles. Cells metabolise carbohydrates and fats to generate Adenosine triphosphate (ATP), the immediate source of energy in tissue. ATP and other important phosphates give rise to MR detectable signals which we study. From these, we derive the metabolic state and cellular pH values.
The relatively slow process of data acquisition in MR requires to take motion into account, especially in organs like the heart. We develop techniques that use MR images to automatically detect and track motion. This requires very rapid acquisition and reconstruction of images.
The biomechanical properties of the myocardium strongly influence the pumping efficiency of the heart. In a current project we develop fully non-invasive measurement of mechanical work of the heart muscle.
