Examples of EAT volume quantification in three cohorts–Examples of measuring and comparing EAT volumes at the same slice in paired CT datasets of three cohorts. Each cohort includes CT images in left panel and EAT highlighted in red in the right panel which was semi-automatically quantified using radiodensity threshold of − 190, − 30 HU. Panel (a–f): Cohort 1, ECG-gated cardiac NCCT (120 kVp) vs. non-ECG-gated chest NCCT-1.25 mm (120 kVp) & chest NCCT-5mm (120 kVp); Panel (g–l): Cohort 2, ECG-gated cardiac NCCT (120 kVp) vs. non-ECG-gated chest NCCT-1.25 mm (100 kVp) vs chest NCCT-5mm (100 kVp); Panel (m–x): Cohort 3, non-ECG-gated chest NCCT-1.25 mm (120 kVp) vs. chest CECT-1.25 mm in arterial phase (120 kVp) & chest CECT-1.25 mm in venous phase (120 kVp), and non-ECG-gated chest NCCT-5mm (120 kVp) vs. chest CECT-5mm in arterial phase (120 kVp) & chest CECT-5mm in venous phase (120 kVp). Abbreviation: EAT = epicardial adipose tissue, see others in Table 1
