Fig 6. Scatter plots and fitted regression line of ssT1-derived Ktrans on fpT2*-derived Ktrans. The Pearson correlation coefficient for gliomas is high and estimated to be 0.95 (95% CI [0.89, 0.98]); however, no linear correlation exists between fpT2* and ssT1 Ktrans values for meningiomas, with the Pearson correlation coefficient estimated to be 0.16 (95% CI [0.68, 0.81]).
