Table 2:

The P values in the last column show results the from paired t test analysis on log(K^trans) in pig brains estimated from DCE-MR^{^a}

↵a The t test demonstrated significantly higher values after intravenous infusion of nitroglycerine in 6 of 8 animals. The columns −NTG and +NTG represent back-transformed values with and without nitroglycerine, respectively.
↵b Significant.
