- The development of the fast spin-echo (FSE) pulse sequence helped revolutionize magnetic resonance (MR) imaging. As its name implies, FSE imaging is faster than conventional techniques. It decreases scan time and increases patient throughput, an economically desirable situation. Shorter scan times decrease patients’ anxiety and motion.www.barrowneuro.org/for-physicians-researchers/education/grand-rounds-publi…

TSE/FSE - Questions and Answers in MRI
The FSE/TSE pulse sequence (illustrated above) superficially resembles a conventional spin-echo (CSE) sequence in that it uses a series of 180º-refocusing pulses after a single 90º-pulse to generate a train of echoes.
MRI sequences: fast spin echo | e-MRI - IMAIOS
Fast spin echo. In fast spin echo sequences, the interval of time after the first echo is used to receive the echo train, to fill the other k-space lines in the same slice. Because of the reduced number of repetitions (TR) required, the k …
