Text: The 100-kVp protocol had a nonsignificantly higher mean vessel attenuation than the 120-kVp protocol (386. 8 HU + / - 130. 1 vs 317. 9 HU + / - 112. 5 ; P =. 56) and a nonsignificantly higher image noise (16. 9 HU + / - 5. 8 vs 13. 7 HU + / - 6. 2 ; P =. 84), which resulted in almost identical SNR (25. 3 + / - 11. 7 vs 27. 0 + / - 14. 5 ; P =. 37) and CNR (22. 0 + / - 11. 2 vs 22. 9 + / - 13. 1 ; P =. 51).
