Fast spin echo RARE FAISE or FSE 10 11 12 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 during each echo time TR interval and the phase encoding gradient is briefly switched on between echoes 13

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 space is filled faster and slice acquisition time is reduced

May 22 2022 The use of fast or turbo spin echo FSE TSE imaging has become routine in MRI today A spin echo sequence employs a 180 RF pulse typically to create the echo which also corrects for dephasing effects from slight field inhomogeneities and chemical shift
Fast spin echo FSE imaging also known as Turbo spin echo TSE imaging are commercial implementations of the RARE Rapid Acquisition with Relaxation Enhancement technique originally described by Hennig et al in 1986 Since that time FSE TSE has grown to become one of the workhorse pulse sequences used in virtually all aspects of modern
