✦ Synopsis

In equations describing multiple spin-echo pulse sequences, the T1 dependence is often approximated by a saturation-recovery expression, which is valid only when the repetition time TR is much greater than the time required for the echoes. A slight modification of this approximation greatly increases its accuracy for small TR values.

## Abstract The fast spin‐echo (FSE) sequence is frequently used as a fast data‐readout technique in conjunction with other pulse sequence elements, such as in fluid‐attenuated inversion‐recovery (FLAIR) and double inversion‐recovery (DIR) sequences. In order to implement those pulse sequences, an
