  1. The T1 values were determined from the fitting of the hyperpolarized magnetization decay curves taking into account the decay by T1 relaxation and RF pulsing. The data were collected using 5 degree pulse angle and repetition time of 5 s. The samples did not contain Gd3+.
  2. aAn average of three runs.
