Importantly, patients research project involving targeted MRI liver disease. I with early liver disease and stage 0 or stage 1 fibrosis demonstrate elevated liver stiffness measurements of approximately 3.5–4.0 kPa. Using a cut-off value of 2.93 kPa, Yin et al. achieved remarkable sensitivity of 98% and specificity of more than 99% for differentiating any stage of liver fibrosis from normal liver tissue.
