A clinical strategy to improve the diagnostic accuracy of 1.5-T non-contrast MR coronary angiography for detection of coronary artery disease: combination of whole-heart and volume-targeted imaging.

• 1.5-T non-contrast MRCA with combined whole-heart and volume-targeted imaging can detect CAD with high sensitivity and moderate specificity comparable with coronary CTA. • Compared with whole-heart imaging alone, combined imaging provides improved diagnostic accuracy, especially specificity.
