Table 3.

Mean value (±standard deviation) and percent error induced in the amide proton exchange rate (k_sw) or the semi-solid proton volume fraction (f_ss) by errors in the water T1 (T1_w), water T2 (T2_w), semi-solid T2 (T2_ss) and B1 parameters considered individually and in all possible combinations.
