CORONARY ANGIOGRAPHY WITH MAGNETIZATION-PREPARED T-2 CONTRAST

A magnetization-prepared, T-2-weighted sequence (T-2 Prep) is used to suppress muscle and venous structures. When combined with lipid suppre ssion, this technique improves the visualization of the coronary arter ies. T-2 Prep was designed to be robust in the presence of flow as wel l as B-0 and B-1 inhomogeneities and may be combined with virtually an y imaging technique. Here, it is implemented with both a single-slice spiral acquisition and a multi-slice spiral method that acquires up to 15 slices in a single breath-holding interval.
