Effect of TE and TR on CBV accuracy with flip angle = 60°. A, Percentage error in CBV estimation for different TEs by using TR = 1.0 second without preload. B, Percentage error in CBV estimation for different TEs by using TR = 1.0 second with ¼ dose preload. C, Percentage error in CBV estimation for different TRs with a 60° flip angle and TE = 35 ms with no preload. D, Percentage error in CBV estimation for different TRs with a 60° flip angle and TE = 35 ms with a ¼ dose preload.
