Fig 1 — Most recent MR study (4 y after the first MR study). Original 3D TOF MRA images at the level of suprahyoid bone (A), at the level of hyoid bone (B), and 3D TOF MRA MIP images (C), which were taken at the beginning of MR study, showed that the right internal carotid artery (arrow) and the right common carotid artery (arrowhead) were displaced medially. T2-weighted axial image at the level of the suprahyoid bone taken 6 minutes after the first sequence, showed that the right internal carotid artery (arrow) remained unchanged, whereas T2-weighted axial image at the level of the hyoid bone (E) showed that the right common carotid artery (arrowhead) had moved laterally to its normal position. In the MR-DSA MIP image (F) taken 20 min after the first sequence, the right internal carotid artery (arrow) is located medially and the right common carotid artery (arrowhead) is located laterally, which coincide with the findings of T2-weighted images (D, E).
