Table 2. Intraobserver and Interobserver Variabilities in and Agreements for SWT and Imaging Biomarkers.

Parameters	Intraobserver	Interobserver
SWT (%)
SWT at baseline	−0.6 ± 5.3 (rIC = 0.93)	0.5 ± 6.2 (rIC = 0.92)
SWT at follow-up	−0.8 ± 5.9 (rIC = 0.92)	0.3 ± 7.0 (rIC = 0.90)
Improved SWT	−0.2 ± 4.4 (rIC = 0.95)	−0.1 ± 4.6 (rIC = 0.94)
ECV (%)	0.2 ± 2.8 (rIC = 0.97)	−0.4 ± 3.0 (rIC = 0.97)
TEI (transmurality, %)	−0.7 ± 6.3 (rIC = 0.95)	−1.0 ± 7.2 (rIC = 0.93)
RIM (mm)	−0.1 ± 0.9 (rIC = 0.93)	0.3 ± 1.1 (rIC = 0.92)

Data are presented as differences (intraclass correlation coefficient r_IC). ECV = extracellular volume fraction, RIM = unenhanced rim thickness, SWT = segmental wall thickening, TEI = transmural extent of infarction
