By using iterative reconstruction and the field map from the sequential spiral-in and out images, the blurring in spiral imaging can be corrected effectively. The combination of spiral in and out improves the image quality around the susceptibility affected region. This technique can be used for fMRI when the regions of interest suffer from susceptibility induced artifacts.
