Multi-contrast atherosclerosis characterization (MATCH) of carotid plaque with a single 5-min scan: technical development and clinical feasibility

Table 4 Slice-based composition analyses: MATCH vs. Conventional protocol

		Conventional Protocol (T1-w TSE, T2-w TSE, TOF)
		LRNC		IPH		CA		LM

# of slice in agreement (%)		129 (94.9%)		129 (94.9%)		119 (87.5%)		126 (92.6%)
Kappa (p-value)		0.89 (<0.001)		0.83 (<0.001)		0.70 (<0.001)		0.78 (<0.001)

LRNC: lipid-rich necrotic core; IPH: intra-plaque hemorrhage; CA: calcification; LM: loose matrix. +: detected; -: undetected.
Note: the plaque with IPH detected was also counted as a plaque with LRNC.
