The pattern of MCA plaque wall distribution on HR-MRI. The white arrow points to the plaque in a cross-sectional image. The intersection of two dashed lines at the luminal center groups each cross-sectional image into four quadrants. The plaque in the imaging cross section may locate at the superior, inferior, ventral, or dorsal wall, respectively. HR-MRI, high-resolution magnetic resonance imaging; MCA, middle cerebral artery.
