Fig. 6.
Comparison of the classic model and the Pell model. a and b. Simulated Fc and Fp, and CBFc/CBFP at 7 T, respectively. c and d. Simulated Fc and Fp, and CBFc/CBFP at 9.4 T, respectively. Solid lines in a and c represent the classic model, while dotted lines represent the Pell model. Black, red, and blue represent tissue T1 of 1.4, 1.6, and 1.8 s, respectively.
