In comparison with other fast gradient-recalled echo imaging techniques designed for enhanced T-2 contrast, this method is more robust with respect to radiofrequency field inhomogeneity and less sensitive with respect to motion artifacts. Three-dimensional parametric images may be calculated using least-squares fitting based on a simple model for steady-state longitudinal magnetization during the imaging sequences.</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:A1997XZ55600003</style></accession-num><notes><style face="normal" font="default" size="100%">Times Cited: 0</style></notes></record></records></xml>
