Using a fast version of selective inversion recovery, we have obtained coronary angiograms of normal volunteers showing the proximal portions of the left coronary artery. Blood is tagged in the aortic root at end systole using a 2D inversion pulse. After a wash‐in time of 300–600 ms, the coronary vessels are imaged with a 2‐ to 3‐cm‐thick slab in either axial or oblique projection. The scan is completed within a breathhold in 24 heartbeats. © 1991 Academic Press. Inc.
