Baseline characteristics of manually segmented fibrous tissue, plaque components and vessel wall

	Presence of plaque component	Volume (mm3) mean ± SD	Area (mm2) mean ± SD
Fibrous tissue	100 % (23/23)	598 ± 327	43.8 ± 26.9
Lipid	43 % (10/23)	108 ± 81	17.5 ± 10.3
Calcification	87 % (20/23)	98 ± 125	12.2 ± 11.7
Loose matrix	65 % (15/23)	133 ± 99	15.8 ± 10.8
Ulceration	26 % (6/23)	35 ± 71	8.7 ± 6.4
Hemorrhage	4 % (1/23)	18	4.6 ± 0.6
Vessel wall	100 % (23/23)	827 ± 541	60.6 ± 41.4

For a given component, the mean volume/area was calculated from the pre-aligned first scan data by taking the average from the patients/slices in which a certain component was identified
