Conclusion

These preliminary data support the hypothesis that a 25% reduced dose of a 0.5-M high-relaxivity contrast material (Gd-BOPTA) is at least equivalent to a single dose of a 0.5-M standard relaxivity contrast material (Gd-DOTA) for routine use in neuro-MRI.

Contrast dosage can be reduced for neurological application of MRI without loss of image quality. This could be important in the management of patient with impaired renal function.
