Comparison of EAT volume and EAT radiodensity between standard ECG-gated cardiac NCCT with 120 kVp non-ECG gated chest NCCT image in Cohort 1, and with 100 kVp non-ECG gated chest NCCT image in Cohort 2, and between chest NCCT and contrast enhancement in arterial phase and venous phase on chest CECT in Cohort 3.
