My research is about improving MRI examinations of the heart and liver in particular. I am also trying to improve the safety of the Magnetic Resonance Imaging (MRI) scanner. A third area of research is to develop the role of the radiographer.
Optimization of magnetic resonance imaging
Magnetic resonance imaging are used for all organs of the body, but my research mainly focuses on optimizing and developing new methods for examinations of the heart and liver. In addition to imaging the organs morphologically, functions and tissue characteristics can be produced, such as strain, blood flows, perfusion, fat deposition and elasticity. By developing these methods, patients can receive faster and safer diagnostics. Radiological examinations are usually carried out by radiographers. By developing the role of radiographer, a better logistics for radiological examinations can be introduced, where the right competence is always available for each examination.
