title: Rapid MR imaging.
abstract: During the past few years major improvements have been made in MR systems resulting in increased S/N, which is now being traded for more rapid imaging times. As discussed, there are three general strategies to decrease acquisition time and more will likely surface. Gradient-echo imaging, which has provided the most clinical experience to date, can be used for rapid imaging, functional studies and unique contrast mechanisms such as susceptibility imaging. While the contrast mechanisms and ultimate clinical utility require further study, it seems likely that gradient-echo imaging will become a routine part of clinical MR imaging.
