Targeted-volume acquisition (A–C) and whole-heart acquisition (D–F). Targeted-volume acquisition showed markedly better image quality in left main and left anterior arteries (scored 4 for A vs 2 for D), moderately better in right coronary artery (scored 4 for B vs 3 for E), and similar quality in left circumflex artery (scored 3 for both C and F).
