Abstract

A method for obtaining magnetic resonance imaging (MRI) echo-planar image (EPI) data, including providing a homogeneous, static background field; providing a gradient field to select a slice of an object for imaging; applying Radio-frequency (RF) pulses to excite magnetic resonance in the selected slice; and measuring a radio frequency signal emitted by the selected slice containing image data. The RF pulses are repeatedly applied separated by a time period shorter than a recovery time of static material in the selected slice such that the static material remains in a state of magnetic saturation, while dynamic material arriving within the slice since a previous RF pulse is not magnetically saturated.
