The relationship between volume of the high intensity signal (HIS) on TOF-MRA MIP images and intraplaque hemorrhage (IPH) volume as measured by multicontrast CMR in HIS-positive plaques (solid circles). The open circles show IPH volumes in HIS-negative plaques with IPH for visual reference (see Figure 3). There was a strong positive correlation between MIP and IPH volumes, though the MIP volumes tended to be larger.
