Abstract

Coronary arteries are small tortuous vessels with physiological motion by respiratory motion and cardiac contraction. The noninvasive imaging of normal and diseased coronary arteries by magnetic resonance (MR) angiography has undergone numerous technical improvements since its introduction in 1993. Early coronary MR techniques used a combination of segmental acquisition of the k-space data and breath-holding. More recent techniques allow use of both electrocardiogram (ECG) triggering and respiratory gating, eliminating the need for patient breath-holding. Thus the acquisition time can be longer than a single breath-hold, and spatial resolution can be increased substantially. Three generations of MR coronary angiography techniques have been described and can be used with or without contrast agents.
