Table 1.

Relaxivity values, r₁, of Mn³⁺- and Mn²⁺-JED recorded in water or human plasma (in parenthesis) at 1.41T, 4.7T^a or 11.7T, 37 °C. Relaxivity of Mn²⁺-JED is much higher regardless of applied field strength.

	Mn³⁺	Mn²⁺	r₁ Mn²⁺/ r₁ Mn³⁺
1.4T	0.5±0.01 (0.9±0.01)	3.3±0.06 (8.0±0.39)	6.6 (8.9)
4.7T^a	0.9±0.02 (1.1±0.05)	4.3±0.32 (3.6±0.21)	4.8 (3.3)
11.7T	0.5±0.01 (0.5±0.02)	2.5±0.08 (1.9±0.08)	5.0 (4.8)

4.7T measurements performed at RT.
