Regarding
nephrogenic systemic fibrosis (NSF), the injected dose level becomes very
important, since NSF is reported to be related to gadolinium chelate
injection in patients with an impaired renal function, depending upon chelate
stability and dose. With gadobenate dimeglumine, a chelate with transient
protein binding and a higher r1 relaxivity became available. Combining a high
relaxivity chelate and 3 T offers multiple opportunities for dose reduction
without loss in image quality. This was proven in a rat brain glioma model at
1.5 and 3 T, comparing half dose gadobenate dimeglumine vs full dose
gadopentetate dimeglumine, a standard extracellular gadolinium chelate.
