Summary
A noninvasive approach to visualize the coronary arteries would be a very desirable asset in clinical cardiology. Over the past few years, magnetic resonance angiography has rapidly evolved to become a feasible modality for imaging of the coronary arteries. However, the technical demands for imaging the coronary arteries are considerable, particularly with respect to cardiac and respiratory motion, and the small size and tortuosity of the vessels. To date, magnetic resonance angiography is only capable of visualizing the proximal course of the coronary arteries. To become a clinical reality, magnetic resonance coronary angiography has to undergo several substantial developments. The necessary advances to be made are: 1) improved breath-hold reproducibility with faster imaging techniques (spiral imaging); 2) sophisticated respiratory gating and triggering techniques by navigator-echo real-time imaging; 3) higher spatial resolution using phased-array body surface coils; and 4) accurate flow-velocity measurements by echo-planar time-of-flight imaging. When these conditions are fulfilled, it is expected that magnetic resonance angiography will further mature into a clinically applicable method for reliable noninvasive imaging of coronary artery morphology and function.
