Figure 1

Diffusion weighted and magnetization transfer contrast images distinguish the thrombus from the underlying plaque. A, T1W image. B, T2W image. C, DW image (b value 450 s/mm²). D, MTC image. E-F, Low and high power Masson’s trichrome staining, respectively. The area of the thrombus (encompassed within the doted lines) and the contours between the thrombus and the plaque (yellow line) are more clearly seen on the DW (high signal) and on the MTC (low signal) images. The presence of a platelet and fibrin-rich thrombus superimposed on the plaque is verified histologically. Asterisks indicate the lumen.
