Pearson correlation analysis between Ki-67 index and MRI relaxation time constants in brain glioma patients, using median value inside (N = 22. N(lesions) = 83).

Age and Gender were evaluated with Pearson correlation, while other MRI variables were evaluated with model Ki67~VariableMRI VARIABLE+Age+Gender-1. Only Age and FLAIR were found to have statistically significant correlation after correction for multiple comparisons over evaluations on basic statistical descriptors.
