Comparison of the plaque characteristics between patients with different types of CoW. (Top) In the A-CoW group, patients with incomplete A-CoW showed a higher enhancement ratio (P = 0.002), and enhancement grade (P = 0.01) compared with the patients with complete A-CoW. (Bottom left) Patients with incomplete A-CoW also showed a higher normalized wall index (NWI) compared with those with complete A-CoW (P = 0.018). (Bottom right) In the P-CoW group, patients with incomplete symptomatic side P-CoW showed a higher probability of high T1 signal (HT1S) compared with those with complete symptomatic side P-CoW (P = 0.013)
