Table 1.

Relaxivity (mM⁻¹s⁻¹) of EP-2104R and CLP measured at 1.4 T, 37 °C in pH 7.4 50 mM Tris buffered saline (TBS), in 5 mg/mL fibrinogen / TBS solution, or in 5 mg/mL fibrin gel in TBS. Relaxivities are reported per molecule. Each probe has 4 Gd per molecule and per Gd relaxivity is the reported value divided by 4. Uncertainty in relaxivity is ± 6% based on repeated measurements in our lab.

	TBS	Fibrinogen solution	Fibrin gel
EP-2104R	39.4	39.2	71.4
CLP	38.5	41.9	44.2
