MRI is an excellent way to visualize soft tissue in humans. The images may contain different contrasts for different tissue types so that abnormalities or pathologies can be found. MRI, on the other hand, is qualitative, there are no absolute numbers, hence the images are usually interpreted subjectively. Quantitative MRI is a new way to image patients where objective measurements are key. I work with various projects to support researchers to obtain, analyse and use these numbers.
