摘要： A method of generating three-dimensional T1 and T2 maps for steady state imaging involves acquiring a first set of spoiled gradient echo images with contrast dependent on T1. A second set of fully refocused gradient echo images with contrast dependent upon T1 and T2 is then acquired. A T1 map is generated from the first set of images and a T2 map is generated from the second set of fully refocused gradient echo images and the T1 map.
