MAGNETIC RESONANCE METHOD AND DEVICE

摘要

The invention relates to a method for magnetic resonance imaging (MRI) of at least a portion of a body placed in a stationary and substantially homogeneous main magnetic field. According to this method nuclear magnetization is excited within a spatially restricted navigator volume by subjecting said portion to a navigator sequence (NAV), from which MR navigator signals are measured. Thereafter, the nuclear magnetization within said navigator volume is transformed back into longitudinal magnetization by subjecting said portion to a navigator unlabeling sequence (UNLBL). Finally, a series of MR imaging signals is generated by subjecting said portion to an imaging sequence (TFE). These MR imaging signals are measured for reconstructing an MR image from said signals.
