Text: Vessel attenuation was significantly higher in group 2 than in group 1 (ascending aorta : 456 83 HU vs. 370 78 HU, p < 0. 001 ; pulmonary artery : 468 118 HU vs. 411 91 HU, p = 0. 03 ; left coronary artery : 437 110 HU vs. 348 89 HU, p < 0. 001), however, there was no significant difference in SNR (13. 2 7. 6 vs. 14. 5 7. 5, p = 0. 49) or CNR (13. 8 6. 6 vs. 15. 9 7. 7, p = 0. 25).
