Abstract

This paper describes a method to fabricate gadolinium hydroxide (Gd(OH) 3 ) nanoparticles. An opaque solution was prepared by adding basic anion exchange resin (BAER) to a Gd(NO 3 ) 3 aqueous solution at room temperature and aging the solution for 12-24 h; the solution became basic because of the exchange of H 2 O with OH - . The particles in the opaque solution have a needle structure, and their crystal structure was hexagonal Gd(OH) 3 . Their longitudinal and lateral average particle sizes tend to increase in the ranges of 175.0-222.1 and 33.9-52.3 nm when the aging time increases from 12 to 24 h, respectively. The relaxivity value for T 1 -weighted imaging was 0.79 mM -1 s -1 for the solution that was prepared at the aging time of 18 h, which was ca. 20% of that for a commercial Gd complex contrast agent.
