Keywords: System Imperfections: Measurement & Correction, Diffusion Tensor ImagingDiffusion MRI provides useful microstructural information of the soft tissue. Scans using a single-shot Spiral trajectory have demonstrated better geometric fidelity and SNR than those with a Cartesian EPI counterpart. This study shows that the field drifting during a diffusion scan can be a confounding factor to the image quality. A correction strategy exploiting the average off-resonance measurement before and after a scan was applied to mitigate the blurring artifact caused by field drifting.
