Abstract

Reversed spiral imaging is discussed as an approach that provides strong intrinsic T-2* contrast without the need for long repetition times. In comparison to the conventional forward spiral method, the T-2* contrast achievedby reversing the spiral k-space trajectory is similar and differs only forvery fast relaxing species. The flow and motion sensitivity of the reversed approach is the same if flow compensation is applied, except for a flow-dependent voxel shift and the sign of the artifact pattern. By simulations as well as phantom and in vivo experiments, it is shown that the image quality in reversed spiral imaging is comparable to that obtained with the forward spiral method.
