Relationship between putamen magnetisation transfer ratios (MTR) in PBC patients and cognitive symptoms in PBC patients. (a) Correlation between magnetisation transfer ratio level and PBC‐40 Cognitive Domain score. (b) PBC‐40 cognitive domain scores in PBC patients defined as having normal and low Putamen magnetization transfer ratio values (based on a cut‐off of lower level of normal based on data from normal control group. All PBC patients with low putamen magnetisation transfer ratio values had moderate severity cognitive domain scores (the highest severity seen for the cohort of patients enrolled in this study).
