Stereoscopic imaging with two tilted projections provides a fast alternative to lengthy 3D acquisitions for the visualisation of vascular structures during MR-guided vascular interventions. Here, a double-echo stereoscopy sequence is used in both phantom and animal experiments, and the quality of the 3D perception is evaluated.
