Recently developed techniques have enabled low susceptibility-artifact imaging near metal implants using conventional spin-echo acquisition strategies. Previous demonstrations of these techniques have been presented at 1.5T. While the susceptibility artifact mitigation of these techniques remains sufficient at 3T, here we address the effects of reduced B1 wavelength applied at 3T. These effects introduce increased B1 artifacts near metal implants, particularly those with long axes oriented collinear with B0. Finite element simulations and phantom images are presented to demonstrate and discuss these effects.
