The purpose of this study was to develop a standard 0.014-inch
intravascular magnetic resonance imaging guidewire (MRIG), a
coaxial cable with an extension of the inner conductor, specif-
ically designed for use in the small vessels. After a theoretical
analysis, the 0.014-inch MRIG was built by plating/cladding
highly electrically conductive materials, silver or gold, over the
inside and outside of the coaxial conductors. The conductors
were made of superelastic, nonmagnetic, biocompatible mate-
rials, Nitinol or MP35N. Then, in comparison with a previously
