Abstract
In order to enable the application of a forcible recovery pulse to the multi-slice technique, when selective inversion pulses satisfy the CPMG condition or the CP condition and ETL (Echo Train Length) is even, a dummy selective inversion pulse is applied at the end of each pulse sequence of the fast spin echo technique for each slice, then a dummy read axis gradient is applied without acquiring MR data, then a refocusing pulse selective of only the current slice is applied, and subsequently a forcible recovery pulse sequence FR selective of only the current slice is applied.
