Approaches to fast MR imaging.
Fast MR scanning may be accomplished through a number of strategies as discussed below. Each technique accomplishes improvements in scan time at the expense of signal and noise, spatial resolution, contrast resolution or other imaging artifacts. The scanning strategies discussed are in a variety of stages of clinical implementation, although several are already in wide spread use. All the existing techniques offer improvements in scan time, but they are still far from the theoretical limits imposed by the physics of MR scanning and further reduction in MR scanning time maybe expected in the future.
