Magnetic resonance imaging of rhesus monkeys before contrast injection and at 2 h and 2 days after injection of Magnevist at 0.1 mmol Gd/kg (left) and PG-Gd 0.01 mmol Gd/kg (right). Enhancements of blood vessel, heart, kidney and liver are clearly visualized at 2 h after PG-Gd injection at a tenth of the dose of Magnevist. By 2 days, the contrast agent has been mostly cleared with both contrast agents. (reprinted from ⁵⁹³ with permission from Wiley.)
