Clinical MRI sequences for imaging near metallic implants are mainly multi-spectral approaches, with fast spin-echo acquisitions and large acceleration factors to achieve clinically relevant scan times. The authors previously reported a broadband, low flip angle method at 1.5T and 3T to image with large field inhomogeneity, such as near metallic implants, quickly relative to non-spatially selective multispectral approaches. Herein, modifications to the previous approach, dual polarity missing pulse steady-state free precession, are presented which achieve high spatial resolutions at 7T with a large 3D FOV in ~5 minutes.
