Non-invasive measurement of liver fibrosis in chronic liver disease (CLD) remains an unmet clinical need. We have developed a Fine Texture Analysis technique (wavelength analysis of fine texture wavelengths below the resolution limit of clinical MRI) and applied this technique to specially acquired MR data to evaluate the capacity for detecting liver fibrosis (LF). LF should alter the normal background liver texture to produce gradient stages of signature wavelength distributions as the coarser fibrotic texture replaces the finer vascular normal texture. Our results show good correlation between clinical assessment of disease stage and spectral features, supporting our hypothesis.
