Matched MP-RAGE image slices and histology specimens with IPH contours. (a) Coronal MP-RAGE slice of the left carotid artery; (b) axial MP-RAGE slices within the out wall boundary at the blue line levels in (a) with IPH contours (red line) generated semi-automatically using 2.2 times the median intensity as the intensity threshold (MATLAB, R2010b, US); (c) matched histology specimens with IPH outlined (blue line). Red asterisk in (b) indicates lumen
