Figure 1

Representative scan-rescan V-V images (rows) of three plaques (columns). The white points indicate the carotid lumen; the white arrows point to the outlined lumen and outer wall boundaries. Green indicates K^trans with a range from 0 to 0.2 min⁻¹ and red indicates v _p with a range from 0 to 1. Minor mis-resgistrations were occasionally present. The K^tran and v _p values shown in each figure are the measurements of the whole plaque.
