One patient with co-existing intracranial and extracranial carotid artery atherosclerotic plaques. In the left common carotid artery (CCA), an eccentric plaque was found on multiple planar reconstructed (MPR)-oblique and MPR-axial MERGE and SNAP images (arrows). The plaque in left CCA showed hyperintense on SNAP image, indicating presence of IPH. In the same patient, an eccentric plaque was found in the left middle cerebral artery (MCA) on curved reconstructed MERGE and SNAP images (arrows) and corresponding MPR-axial images (lower right corner). The plaque in left MCA appeared hyperintense on SNAP image, indicating presence of IPH
