Abstract

Contrast‐enhanced (CE) MR angiography of the right coronary artery (RCA) was performed using 2D thick‐slice projection imaging with a small (8 mL) intravenous injection of contrast agent in six volunteers. With a tight contrast bolus injection, the RCA was enhanced for a few seconds after the contrast bolus was washed out of the right ventricle. This allowed data to be acquired when only the RCA was enhanced. Using 2D thick‐slice magnetization prepared steady‐state free precession (SSFP) imaging, background signal was suppressed and a complete data set was acquired in three heartbeats. A mean vessel length of 7.1 ± 0.9 cm was depicted with a signal‐to‐noise ratio of 11.8 ± 0.7 and contrast‐to‐noise ratio of 6.1 ± 0.6. Thick‐slice 2D projection CE SSFP is a promising method to depict the RCA. Magn Reson Med 52:699–703, 2004. © 2004 Wiley‐Liss, Inc.
