摘要：

A flow‐independent method for imaging the coronary arteries within a breath‐hold on a standard whole‐body MR imager was developed. The technique is based on interleaved spiral k‐space scanning and forms a cardiac‐gated image in 20 heartbeats. The spiral readouts have good flow properties and generate minimal flow artifacts. The oblique slices are positioned so that the arteries are in the plane and so that the chamber blood does not obscure the arteries. Fat suppression by a spectral‐spatial pulse improves the visualization of the arteries.© 1992 Academic Press,Inc. Copyright © 1992 Wiley‐Liss, Inc., A Wiley Company
