Artifact in SE phase images can mimic aortic dissection.
Phase images of cardiac-triggered thoracic spin-echo scans can present an artifactual border-like feature across the aorta. This may be misinterpreted as a dissection. The artifact results from helical flow in the aorta; cause and appearance of the artifact are discussed.
