Figure 3 The thrombus revealed characteristic time-dependent changes in its appearance in T2-weighted (T2W) and T1-weighted (T1W) images in the sequential magnetic resonance (MR) scans reflecting the course of the signal intensity. Axial black-blood T2W (A, C, E) and T1W (B, D, F) MR images demonstrating the changes of the MR signal intensity of the thrombus over time. The difference in the MR signal between the thrombotic artery (arrow) and the adjacent muscle is particularly evident during the first three weeks. Bar scale = 1 cm.
