Rapid renal excretion of GdGN was observed in mice within 1 h with no accumulation in the liver. GdGN did not migrate across the BCFB in normal mice, thus emphasizing its safety as an MRI contrast agent. STATEMENT OF SIGNIFICANCE The authors developed ultra-small sized gelatin nanogels as blood-brain-barrier impermeable contrast agents for magnetic resonance imaging (MRI). The authors used radiation crosslinking technique to ensure better integrity of the amino acids present in the gelatin nanogels while conjugating with g
