Assessment of plaque burden and plaque composition. Multiplanar reformations (MPRs) derived from the baseline scan (A1 and B1) and the follow-up scan (A2 and B2) were co-registered and the presence of plaque and plaque morphology was evaluated. Slice A shows the development of a new noncalcified plaque in a slice without plaque at baseline. Slice B shows the change of plaque morphology from noncalcified to calcified plaque.
