Figure 1.

Multisequence MRI of the internal carotid artery at 3 different levels: first column; time-of-flight (TOF), second column; T1-weighted turbo-spin echo (T1), third column; T2-weighted turbo-spin echo (T2); and fourth column; proton density-weighted (PD). Top, Most caudal transaxial projection demonstrating A. communis (arrow). Middle, Intermediate transaxial projection demonstrating C. interna (arrowheads) and C. externa (open arrows). Bottom, Most cranial transaxial projection demonstrating C. interna (arrowheads) and C. externa (open arrows). Note the reduced blood flow on TOF in C. externa (middle) and C. interna (bottom). Plaque buildup can be seen in C. externa in T1, T2, and PD (middle) and in C. interna in T1, T2, and PD (bottom).
