Objective Blood oxygenation can be measured using magnetic resonance using the paramagnetic effect of deoxy-haemoglobin, which decreases the T 2 relaxation time of blood. This T 2 contrast has been well characterised at the B 0 fields used in MRI (1.5 T and above). However, few studies have characte...
