Meta-analysis: noninvasive coronary angiography using computed tomography versus magnetic resonance imaging.

Background: Two imaging techniques, multislice computed tomography (CT) and magnetic resonance imaging (MRI), have evolved for noninvasive coronary angiography.

Purpose: To compare CT and MRI for ruling out clinically significant coronary artery disease (CAD) in adults with suspected or known CAD.

Data Sources: MEDLINE, EMBASE, and ISI Web of Science searches from inception through 2 June 2009 and bibliographies of reviews.
