Figure 3 Representative multispectral magnetic resonance images of echolucent carotid plaques. (A) High-resolution B-mode image of carotid atheroma as shown by gray arrowheads. CCA = common carotid artery; ICA = internal carotid artery. (B) Presence of echolucent plaque visualized by Doppler-ultrasound. (C) Short-axis Doppler-ultrasound image of carotid atheroma. (D) T1-weighted (T1W) image. (E) T2-weighted (T2W) image. (F) proton density-weighted (PDW) image. (G) Time-of-flight (TOF) image. White arrowheads indicate adventitia of carotid artery, and the asterisk indicates the carotid vein.
