All images were created with a 3T MRI and 16-channel head coil. a 3D axial T2-weighted image of atherosclerotic plaque (white arrow) at the vertebrobasilar junction in a patient who presented with a transient ischemic attack. Note the juxtaluminal T2 hyperintensity, depicting the fibrous cap. b 3D axial T1-weighted image post-contrast showing eccentric vessel wall enhancement, consistent with a recently symptomatic atherosclerotic plaque, and outward remodeling of the plaque. c Digital subtraction angiogram of the same patient in (a) and (b), showing a lateral view of the atherosclerotic stenosis at the vertebrobasilar junction. d Diffusion-weighted image and apparent diffusion coefficient axial images of a second patient who presented with left-sided weakness and was found to have an acute ischemic stroke in the right internal capsule (white arrows). e TOF MRA shows minimal stenosis in the right M1 segment (white arrow) of the middle cerebral artery, at the origin of the lenticulostriate perforators that supplied the distribution of the ischemic stroke. f Sagittal reconstruction of the same right M1 segment again demonstrates eccentric wall enhancement, consistent with recently symptomatic atherosclerotic plaque, and outward remodeling at the site of the enhancement
