Abstract

This study was an attempt to see the possibility of a silicon brass for application in high field MR-guided biopsy application. The α + β phases silicon brass was found to have matched strength and toughness, and also showed acceptable corrosion resistance and Cu ion dissolution in short-term immersion test. It was found that silicon brass presented diamagnetic property with a low volume magnetic susceptibility, which is possible to reduce the magnetic susceptibility artifact (MSA). The artifact of silicon brass showed slightly larger than pure copper, but much less than pure titanium, located in both parallel and perpendicular to the direction of a 3-T magnetic field used in fast spin echo (FSE) scan sequence. In conclusion, the silicon brass is a promising material for application of high field MR-guided biopsy needles.
