Distribution of SI differences (postcontrast SI—precontrast SI). In grey matter and white matter, there was no significant difference in SI, and in tumour lesions, the difference in SI in the 5.0 T group was significantly greater than that in the 3.0 T group. The yellow line represents the 25%-75% confidence interval. The yellow line depicts a range within the 1.5 interquartile range. The white dot represents the median
