Fig 4.
Regression plots of rCBF values measured on pre-acetazolamide (-pre) and post-acetazolamide (-post) 123I-IMP and FAIR images. All plots show a significant correlation between 123I-IMP and FAIR results. A better correlation coefficient is observed between the findings on pre-acetazolamide 123I-IMP images and FAIR images obtained with a TI of 1400 milliseconds. On post-acetazolamide images, a higher correlation is observed between 123I-IMP images and FAIR images obtained with a TI of 1200 milliseconds.
