Fast echo formation
WebJul 2, 2001 · A novel spin-echo-based refocusing strategy called a hyperecho mechanism is introduced by which the full coherence of magnetization submitted to a sequence of arbitrary RF pulses can be reinstalled. First implementations illustrate the potential of hyperecho formation—especially for Rapid Acquisition with Relaxation Enhancement (RARE) … WebFast spin echo Fast spin echo (FAISE or FSE, ref 65bis), also called turbo spin echo (TSE) is an MRI sequence that results in fast scan times. In this sequence, several 180 refocusing radio-frequency pulses are delivered …

Sound waves can bounce off smooth, hard objects in the same way as a rubber ball bounces off the ground. Although the direction of the sound changes, the echo sounds the same as the original sound. Echoes can be heard in small spaces with hard walls, like wells, or ...

Gradient echo sequences form the basis for an essential group of imaging methods that find widespread use in clinical practice, particularly when fast imaging is important, as for example in cardiac MRI or contrast-enhanced MR …
WebThe basic principles of spin echo formation are relatively simple and clear. However, description and evolution of magnetization becomes much more exciting and interesting with the use of several refocusing pulses as used in fast spin echo techniques such as TSE, RARE, or FSE.
