By using phase-directional information from a single two-dimensional phase-contrast sequence, we were able to show that the direction of flow in the affected vertebral artery was reversed. The same vertebral artery showed no signal on a 2-D time-of-flight sequence with a concatenated presaturation pulse applied above each section.}, issn = {0195-6108}, URL = {https://www.ajnr.org/content/15/9/1642}, eprint = {https://www.ajnr.org/content/15/9/1642.full.pdf}, journal = {American Journal of Neuroradiology} }
