Reference	Year	Procedures n	MR plaque imaging sequence	Definition of plaque characteristics	Plaque characteristics (category and number)	New DWI lesion	Slow-flow phenomenon	Any new stroke
Sakamoto et al. [13]	2010	31	T1W, T2W, TOF	Presence of main components (IPH, LRNC);	Vulnerable plaques: 14	6	8	1
				Presence of main components (Fib, CA)	Stable plaques: 17	10	2	1
Yamada et al. [20]	2011	56	T1W	SIR ≥1.25	High SIR group: 28	17	NG	2
				SIR <1.25	Low SIR group: 28	6	NG	0
