Abstract: The disclosed invention is a method for detecting indications of the presence of liver disease and other fibrotic diseases using a magnetic-resonance based technique for measuring fine tissue and bone textures. Specifically, the invention focuses on adaptations to this prior art to facilitate assessment of the presence and severity of liver disease, lung disease, and other fibrotic disease by measuring spatial wavelengths characteristic of the specific disease process across an areal cross-section through an organ. The results may be presented using a mapping technique. In this way, the resolution of MR is extended further than possible with current MR imaging, so as to be able to measure the fine scale structures and tissue changes that are known to be characteristic of the degenerative processes involved in the development of these diseases.
