1 Example of discordance between the standard approach and HR-MR imaging.
Example of discordance between the standard approach and HR-MR imaging. Suspicion of spontaneous acute dissection in a 47-year-old woman with postchiropractic right neck pain and transient dizziness, without stroke. Findings of DUS were inconclusive (not shown). B, On standard axial fat-suppressed cervical T1WI, note nonspecific hyperintense crescentic mural thickening of the right V3 segment (arrows). A and D, On CE-MRA, note stenosis (arrow, A) of the right V3 segment, which was partially resolved on 1-year follow-up CE-MRA (D, arrow). C, Coronal high-resolution T1WI, obtained 24 hours after CE-MRA, demonstrates a clear hyperintense crescentic mural thickening of the right V3 segment (arrow). This supports the diagnosis of VAD. O.
