An example of intraplaque hemorrhage seen on a TOF source image in a 71-year-old man with a left cerebral ischemic event. A, Axial source image of TOF MRA shows the IPH (short arrows) in the eccentric left carotid plaque, which surrounds the lumen of the internal carotid artery with severe stenosis. IPH is identified as a hyperintense signal intensity compared with the adjacent neck muscle. B, Lateral projection of a left carotid angiogram shows long segmental severe stenosis in the proximal cervical portion of the left internal carotid artery. C, Postcarotid artery stent placement angiogram shows minimal residual stenosis at the origin site of the left internal carotid artery.
