Note.—Data are mean ± standard deviations.
*P<0.05,
**P<0.01 for comparison with rats in normal group.
# P<0.05 for comparison with rats in mild group.
Ktrans = transfer constant, Kep = rate constant, Ve = extravascular extracellular volume fraction; iAUC = initial area under the gadolinium concentration-time curve.
