Fig. 3A. —Segmental image quality (i.e., per 3 cm) per coronary artery is shown using 5-point grading system (1, nondiagnostic or unreadable; 2, poor; 3, moderate; 4, good; 5, excellent). Because of variable length in visualization of coronary arteries on both sequences, number of visible segments is shown for each sequence at bottom of column. Bar graphs show image quality assessment for left main coronary artery (A), left anterior descending coronary artery (B), left circumflex coronary artery (C), and right coronary artery (D). Dotted bars = turbo-field-echo sequence, white bars = balanced turbo field-echo sequence.
