Examples of outer wall areas, inner wall areas and lumen areas at the proximal sites (a), maximal lumen narrowing (MLN) sites (b) and distal sites (c) that were traced manually in a 53-year-old female patient with basilar atherosclerotic plaque. For the Self-referenced measurement method, the plaque area is 3.42 mm2, stenosis rate is 0.521, and percent plaque burden is 0.254. For the Referenced measurement method, the outer wall area at the reference site is 13.64 mm2, the lumen area at reference site is 6.62 mm2, the wall area at the reference site is 7.02 mm2, the wall area at the MLN site is 10.33 mm2, the plaque area is 3.31 mm2, the stenosis rate is 0.551, and the percent plaque burden is 0.246
