The potential of a single-shot stimulated echo acquisition mode (STEAM) sequence based on RF refocused echoes for DW imaging close to metallic objects is evaluated. It is optimized for spinal cord applications by combining it with inner-FOV technique based on 2D-selective RF (2DRF) excitations and half-Fourier sampling which improves its signal-to-noise ratio (SNR) efficiency significantly. Its robustness in the presence of metallic objects is investigated and compared to EPI showing a better performance with smaller regions suffering from signal losses.
