Dynamic coronary MR angiography and first‐pass perfusion with intracoronary administration of contrast agent

To evaluate whether dynamic imaging of the coronary arteries can be performed with intracoronary infusion of low‐dose gadolinium (Gd)‐based contrast agent and assess the effect of long duration and multiple infusions on the image signal‐to‐noise ratio (SNR) and contrast‐to‐noise ratio (CNR).
