A method of pre-scan data acquisition includes the application of a
pre-scan pulse sequence to acquire MR signals from a region-of-interest
to be imaged with an imaging pulse sequence. The pre-scan pulse sequence
applies a pre-scan readout gradient pulse and a pre-scan readout gradient
rewinder pulse. MR signals are acquired from a region of interest during
application of the pre-scan readout gradient pulse and after application
of the pre-scan readout gradient rewinder pulse.
