Objective:
The purpose of this study was to compare whole-heart acquisition with targeted-volume acquisition in 3-T navigator coronary MR angiography with parallel imaging.
Subjects And Methods:
The right and left coronary arteries of 20 subjects were imaged with axial whole-heart acquisition and two oblique targeted-volume acquisitions.
Results:
Both whole-heart and targeted-volume acquisitions were completed with similar navigator efficiencies ( approximately 50%) and depicted similar coronary artery diameters ( approximately 3 mm) (p >or= 0.06). The lengths of the coronary arteries were not significantly different (p = 0.07-0.45) for the whole-heart and targeted-volume approaches. Depiction of the sharper coronary arteries (p
Conclusion:
For current 3-T navigator parallel-imaging coronary MR angiography, targeted-volume acquisition yields sharper coronary images than does whole-heart acquisition.
