Fast(er) MR imaging.
The author reviews the methods used for rapid MR scanning, including gradient echo, fast spin echo, and planar sequences. Each of these approaches can be understood by evaluation of the relationship of the fundamental MR parameters such as T1 and T2 values to operator selected variables such as TR, TE, and flip angles. Strategies for phase view acquisition and the application of high performance gradients are discussed.
