Bland-Altman plots of assessing the agreement of EAT volume measurements in three cohorts–Comparison of EAT volumes derived from ECG-gated cardiac NCCT (120 kVp) with non-ECG-gated chest NCCT and effects of contrast agent and slice thicknesses on EAT volume quantification in non-ECG-gated chest CT. In Cohort 1 and Cohort 2, EAT volume derived from cardiac NCCT (referent) vs. non-ECG-gated chest NCCT-1.25 mm (Panel a & c), and vs. chest NCCT-5 mm (Panel b & d) images are assessed in Bland-Altman plots for the measurement agreement. In Cohort 3, EAT volume derived from non-ECG-gated chest NCCT-1.25 mm (referent) vs. arterial CECT-1.25 mm (Panel e), and vs. venous CECT-1.25 mm (Panel f), as well as EAT volume derived from chest NCCT-5 mm (referent) vs. arterial CECT-5 mm (Panel g), and vs. venous CECT-5 mm (Panel h) are assessed in Bland-Altman plots.
