Figure 2 Axial black-blood T2-weighted magnetic resonance image showing a 24-h old mural, eccentrically shaped thrombus (A), magnified 2.5x in B. The arrows indicate the thrombus in the injured right carotid artery, and the asterisk indicates the noninjured left carotid artery. The signal from the flowing blood in the lumen is black due to the double-inversion preparatory pulses. The corresponding histologic section is shown in C. The appearance of the thrombus on the magnetic resonance image correlates closely with the matched histologic section shown in C.
