Fig 6. Scatter plots of tumor blood flow between T2DSC and CASL. A, CASL-rCBF versus T2DSC-rCBF. B, Ratio of tumor blood flow relative to whole section values between T2DSC and CASL. Linear regression analyses reveal high correlation in absolute rCBF values and relative ratios. The equation of the regression line is drawn in panels A and B. r2 is the square value of correlation coefficient. Dashed lines indicate 95% confidence bands for the linear regression.
